HOW TO Add Magnets to 3D Prints

How to create your own fridge magnets using 3d printing. We use Meshmixer to plane cut a model, add holes for magnets, then Slic3r PE to do dynamic layer height and custom supports. Then, we 3d print on the prusa i3 mk3 3d printer.

I had no idea that you could block support material for different parts of a model in the slicer. This video was a really big help to me. Thanks.

[@3DPrintingNerd]

Welcome!

[@cathyomalley2772]

Fantastic explanation Joel. Thanks

[@magomat6756]

The old Joel is back yeahhhh. I like it you show the failures.

[@PaulFulbright]

Mind. Blown. Never knew Slic3r could do variable layer height! Thanks man!

[@LPMSupporter]

Congratulations for surpassing 300.000 subscribers Joel!

[@eWingsUK]

YES! CLOSE UP CAMERA! Makes all the difference, nice one!

[@blizatrex]

Making figures into magnets is a great way to make all of in this case Wekster minis and have them be useful.

[@ShiftySushi]

Yay, I ordered a magnet! It's silly how happy that makes me.

[@itsmeintorrespain2714]

Excellent entertainment combined with a well explained "how to". Subscribed.

[@3DPrintingNerd]

Thank you!

[@PeterDalling]

Thanks Joel, a great explanation on using variable layer height and custom supports in Slic3r.

[@jd52wtf]

Should have made them internally captive. Just need a cavity and a pause to pop them in while they are printing. No glue required.

[@hotaru8309]

4:30 "There's easier ways to do everything I do most likely." -Joel I'm sure that extends to this sort of thing as well. Although not having to pause the machine, Joel's way in this video, may be easier in this case.

[@hotaru8309]

Depending on how you feel about pausing and how much your magnet likes your nozzle, it might not work out as cleanly. I think the magnets will work through most materials though, so your idea is certainly an understandable plan.

[@TheThursty100]

That's how I did it. The problem is, while the Nozzle isn't magnetic, the cooling vent I have on my hot end is. And if I don't align the print correctly, or press the magnet down with the tweezers for the first layer, the magnet will attach to the vent, which is no bueno. That said, I wanted to print a new Hotend housing anyways, and as of now, regular old PLA isn't magnetic

[@CJICantLie]

@@TheThursty100 I have seen suggestions to print a cap for over the magnet and have the pause be a bit further up to fit that cap. You put the magnet and the cap in at the pause and it can resume with a material it sticks to as well as limit the magnetic issues.

[@jamesdavis2027]

Its so easy to add the pause with the filament change option in prusa slic3r.

[@mrpotatoheadie]

Hey Joel, quick hint for most CAD software RGB=XYZ... most stick to a red=X, Green=Y and Blue=Z convention. Enjoyed the video!

[@greg6882]

What a great video. This is the kind of video I like. Showing some basic/possibly unknown functions of our programs, making or modifying a cool build. Keep up these kinds of videos!!!! 300k, WooHoo!!

[@nerys71]

yes you can do that in tinkercad (the MMU version) tinkercad WILL remember and retain origin alignments.

[@StephenBoyd21]

Mini Joel looks awesome. Mini Joel magnet looks even more awesome!

[@GdalyaRoth]

Great video! I particularly liked 1. Your beginning to explore meshmixer. I too have been intimidated by meshmixer's complexity and a video like this shows what it can do that other tools maybe can't and provides an on-ramp 2. Bring sure to mention getting someone else's permission before using their stuff. There is a range of experience in our community, so some might think that it's obvious while others might never think to do it

[@owenjones5792]

Just ordered my fridge magnet! Looking forward to getting it and being able to stick mini Joel on my fridge!! Glad the proceeds go to charity!

[@slarti4242]

SOME of the proceeds

[@3DPrintingNerd]

Yes, some! Total announced later this week! Ooh, had to edit because I forgot one thing. I was going to ask - any guesses as to how much we raised?

[@slarti4242]

A lot, hopefully. Look, I don't want to be that guy, but whenever anyone says "some of the proceeds go to charity", I always assume 0.01% goes to charity and the rest somewhere else. I'm sure that's not the case here but we've seen some nasty stuff in the past from all sorts of people. I enjoy watching your videos and I'm sure you really do mean good with this. Just that one little word bothered me, that's all. Hope you raise a lot!

[@3DPrintingNerd]

It is a lot, I promise :)

[@QuiZHI]

Simply awesome. Great work and even greater support for charity. Keep up the great work.

[@TD3DMakes]

I watched this while making a BLT sandwich. The sandwich was delicious. So was this video. Thanks for sharing!

Can't wait to see you at MRRF

[@UrbanNerdOfficial]

Great way to turn a full 3d model into something more! Great video!

[@chicoriver8606]

Nice make a mini Joe zombie magnet. Thanks for the lesson I never use mesh maker and never use the slicer in that way. Thanks for demonstrate what is possible in easy steps

[@Applesupnorth]

Good vid Joel, I especially liked your more detailed approach to recording how you use MeshMixer, and also the detailed approach to Slic3r PE. I think it shows many inexperienced users some key tips, and also not to be afraid to "just try it", as it was obvious even you had/have some "ummmm...sure......, that''ll work....." moments :) It's videos like this that give a lot of ppl invaluable knowledge in this hobby. Keep it up!

[@3DPrintingNerd]

Thank you! I really wanted to approach Meshmixer with a "let's just go for it and see what happens" attitude. I think more people are intimidated by it and won't even experiment. There is always CTRL-Z :)

[@alecalejo7556]

Great Video Joel. Just a couple days ago I had the same thing happen to one my build surfaces now I have the same magnets laying around. This is a great idea and i cant wait to implement it in some future projects.

[@reasonablebeing5392]

Congrats on 300K !! Can't wait to see you again at MRRF.

[@Mitch3D]

Nice cameo of your daughters artwork, she's very good. Meshmixer frustrates me with the Boolean difference like you experienced. I even tried flipping the normals and using that to make a void like the Maker's Muse tutorial

[@rksolar2806]

You have such a great personality, man!

[@tseawell90]

[@Hawk1966]

Excellent video! As the Mythbusters always said "Failure is Always an Option." 😁

[@oldsjunkie1]

Man, you're consistently putting out great useful content that inspires ever more ideas! Glad to see you getting the payback from all the hard work. Really cool community here in 3D printing and i'm glad I got into it. Seeing ideas go from a thought, to the screen and then into a usable part in a matter of hours sparks a creativity overload! I constantly have the bed of my FT-5 packed with jobs and a pile of ideas that makes it clear why so many of you guys have several printers... Add that my girlfriend loves to watch it work and see the results and already says we need a bigger printer so I can run working parts and cute stuff at an equal rate ;) Thanks and keep up the great work Joel! PS: If you weren't so far, my guys would be there taking care of those walls so you can keep slinging plastic...

[@TurboSunShine]

Nice Joel! You should make a video on "embedded" magnets too,(where you pause the print, put in some magnets, and resume the print) like i did on my chainmaie wallet! see my newest video for more info :)

[@Vladlabs]

This is how it had to be done actually. :)

[@ineedgoodname]

Makers muse did a video on how to do that

[@jordongingrich8913]

Another awesome video Joel! Lots of learning

[@Anolition]

This is cool, you should make a giant one

[@thomassutrina7469]

This is a great review of BUILD TECH SHEETS the magnets are ceramic because only ceramic and alnico and only epoxy which is brittle and silicone rubber adhesives can take 375 F. So they didn't get the message on adhesives. A few other adhesives get close but no margin of safety left. They chose cost over reliability.

[@tylermckeon9202]

This is a great video Joel! Please do more "How To" Videos!

[@DavidPeach10]

Yay! I'm going to MRRF for the first time this year. Looking forward to meeting you Joel! (And maybe getting one of those cool granite mini-Joels).

[@gork42]

Hi Joel to improve the quality of boolean difference you generally need to increase the mesh density of the primitives. Turn on wireframe view and select some of the vertices of the box object. Then select modify->select all then remesh to make more faces. After this, the boolean difference will give you better results. Sometimes you need to remesh the object you are cutting too depending on how many faces it's got.

[@3DPrintingNerd]

OOH! Thank you for this tip!

[@gork42]

@@3DPrintingNerd Yeah no problem; I went through a lot of iterations yesterday trying to carve some simple v slots into the base of a model to improve bed adhesion on my Anycubic Photon by breaking up the base into smaller areas that would be less prone to warping. The spheres were making a great cut, but the box and cylinder were just awful, especially when stretched out. Remeshing totally fixed it. I did also get a lot of crashing with Meshmixer as well. Sadly this is not an area where it is a very strong tool.

[@Lamplighterone]

Joel. I loved everything about this. I was anticipating the multicolour jbot! As I'm looking at the Prusa being my next printer, the MMU is one of the contributing factors. I'm hoping to get a multicolour joel bot to get my hands on a prusa mmu print. Thank you for the don't give up moment. My printer is down but I'm waiting on parts. Not giving up. Working on home made art to print. High Five.

"Just use water" will cause the surface to flash cure while leaving the middle uncured. The accelerator will cure all the way through...faster than just letting it absorb water vapor from the air, but slow enough to let the insides cure.

[@swiftrick15]

Hey Joel, that looks great. You should do it again but use flexible filament for the hair. THAT WOULD BE AWESOME.

[@sdhpCH]

Suggestion für part 2 of this video: Get glueless. How: Print some layers (with closed bottom layers!), pause the print, insert the magnets, continue and finish the print. > The magnets are enclosed in the print.

[@phizicks]

Oh don't remind of the snow in Seattle, I had to walk to work for 5 blocks in the slush it left behind.

[@DanteNava]

Sweet shirt!

[@rickseiden1]

I can see how it makes some sense to print them laying down, but couldn't you have printed them standing up and not had to use support, or worry about adjusting the layer height? I think there would have been enough of a base left in the feet to support it.

[@AndrewRuffolo]

I was thinking this same thing... Also you wouldn't have to dynamically change the layer heights.

[@hotaru8309]

1:09 "These are 'History Magnets' right here." We must preserve them, for SCIENCE!

[@authorizeduser6507]

Meshmixer is the only app with a useful multi part AMF export. Select all, export AMF, import one file as multipart for MMU!

[@jermbug2000]

These are nice. Hope to meet you at RepRap festival next month.

[@LincolnWorld]

Atari ET T-Shirt for the win! Is this the second style of ET-T-Shirt you have worn in a video. I think I remember one other one. I was going to point out that you probably want the magnet hole to be not quite as deep as the magnet so it will stick out a bit and have better contact with the fridge, but it looks like you adjusted that for some of the examples. I love making fridge magnets out on the 3D printer! Hi-5!!!

[@RonFloyd]

Really cool Joel! MiniJoels all over the place - HaHaHa

[@OldCurmudgeon3DP]

I would have tried a vertical print. No layer height issues on the belly. This is a cool project though. More things to design/print!!

[@JAYTEEAU]

Great stuff Joel. Catch you at MRRF. Cheers, JAYTEE

[@eugenew2]

I've not used meshlab, and this is 2 years old, but could you create a 12x duplicated object for each of the multi color Joel and boolean at the same location?

[@KieranShort]

a lot of this is so much easier in Slic3r PE v 1.42. Particularly the placement and sizing of the support enforcer/blockers. Currently in Alpha testing..

[@svenvanbeckum6397]

You should get a view on the new alpha on slic3r pe, support blockers get that much easier

you should print the largest flexi rex :D My ender tops out at 288% unfortunately! But he is glorious.

[@ericzwirnmann8151]

Joel, thanks for the tip on how to set up a "blocker" to prevent unneeded supports. Didn't know you could do that with Slic3r. Do you know how to chance the size dimensions of the generic block after you create it? I keep having to remove and try again until I got it right.

[@3DPrintingNerd]

So far, I do not. I think this functionality is changing in the next version to make it easier!

[@jalinert7]

Joel if you look at a solid figure with magnets you see that most of them figure is raised up from the magnet letting it have better contact with the surface it is on. Your first measurement was correct you shouldn't second guess yourself.

[@HenrikLaurell]

I have been following your channel for a couple of months, also subscribed and think it's great! this episode is no exception! I wonder if you could make an episode about y-axis drifting or any drifting for that matter. Have been struggling with that for about 10 days now. I know there is nothing wrong with my printer since other prints works just fine, but as soon as I design and try to print something narrow and a bit high, it fails just miserable ... Tried placing the model in different angles, changing speeds, infills, supports, wall thickness, all I could think of. Would very much appreciate a new perspective on this phenomena ... Thanks /Henrik

[@3DPrintingNerd]

Hey - first - thank you! I appreciate you stopping by and watching what I make! Second - drifting... Are your layer shifting in the Y axis?

[@HenrikLaurell]

@@3DPrintingNerd yes. The model looks "somewhat" ok from the front, but just terrible zigzag looking from the side. And again other models prints ok so feels hard to blaim the printer...

[@3DPrintingNerd]

Hard to tell without seeing some photos. Usually a drift or a shift on all models is caused by a loose pulley on a motor shaft. Can you check the pulley on the Y motor?

[@HenrikLaurell]

@@3DPrintingNerd it's a dremel 3d40 so pretty much inclosed, but wouldn't all models be affected if that was the case ? How can I upload a photo here ? so I can show you.

[@HenrikLaurell]

Last test print was just finished and with a just perfect result! This time I did use the original Print Studio slicer instead of dremels latest Cura clone. Since I started fresh with no settings changed I got all the defaults right. Only thing I changed was to set infill to 100% as in a total solid model. Now it worked -- Hurray !! Odd that I managed to mess up the Cura settings that much... Many thanks for your interest in this matter! /Henrik So what did I print ? It is air vents for a scale model of the swedish monitor Solve from 1875. The model boat will 104 cm long when done.

[@coltenhoehns3229]

[@gibbermagash5559]

So the multi-material model you printed with an extruder than can take 4 different filament colors? Or did you have to pause the print and change the two filaments?

[@3DPrintingNerd]

I did that with the mmu1 from Prusa, it’s takes four!

[@KieranShort]

I saw the printer profile in Slic3r... are you using the original mmu? Do you not have the mmu2? The mk3s announcement, fixing the filament sensor, might make the mmu2 that bit better.

[@3DPrintingNerd]

The original! MMU 1.0!

[@twisted_seraph]

Does the super glue hold. I used gorilla epoxy.

[@dronesrus5676]

Joel this is good stuff but 3D Builder in Windows or Tinkercad might be easier. 3D Builder is great for cutting things up or subtracting holes from an existing model. It is simple like MS paint for 3D models. Check it out sometime.

[@dronesrus5676]

Lol well that’s what I get for commenting before I finished the video. Meshmixer it is.

[@nipap2243]

joel i need help! all 4 of my printers nomater wat i do the print wont stick can you pls make a video on bed adhesion

[@fhuber7507]

Magnets don't like heat. You can demagnetize any manufactured magnet by exposing it to enough heat for enough time. For this reason, I wouldn't try the magnetic build plates. I know they will eventually fail. Rare Earth magnets are notoriously subject to demagnetizing at lower temperature than ferrite magnets. Cobalt holds up to a bit higher temperature than neodynium (neodymium is the type used in most RC hobby brushless motors) ******************** In USA, you can get packages of neodymium appx 1/4 inch diameter appx 1/8 inch thick magnets cheaply at "Harbor Freight" Very good to insert into your small 3D prints. Make your D&D minis stay firmly in place by having a metal sheet under the battlemat. Put a magnet in the base.

[@hot_wheelz]

Hi Joel, great video! I'd love me one of those mmu mini Joel's pretty pretty please. :)

[@uwezimmermann5427]

first view in Meshmixer (2:58) looks like mini-Joel on an operating table ;-) If going through all this procedure - why not design internal cavities and fully hide the magnets inside - with a pause during the print...

[@nerys71]

how are you loading the file into meshmixer without ruining it? when I load any stl into meshmixer it is "decimated" on load to really low resolution. ie the output is crap. what am I doing wrong?

[@3DPrintingNerd]

I dunno, I just load it.

[@eddiegochenour410]

I believe you can press and hold down the space key to pop up the hot box menu. If you let go of space key the menu goes away. With the hotbox open select the middle sphere in the Normals section. Loaded file should then look nice and clean.

[@NicholasMavrikBrandt]

Nice video Joel, is there anyway you can dual upload to LBRY? They have assistance with importing all your KZbin catalog. It would be great to have some 3d Printing love over there. I am just a viewer not part of LBRY except a user. There is no 3d printing videos to watch its sad. Barnacles video with you is about as 3d printing as it gets.
