Command Strip Handles | Design for Mass Production 3D Printing

[@larscarlsen5860]

you are making some pretty unique content, got me pretty pumped to change some of our machined items to 3d prints

[@slant3d]

Great to hear! Let us know if you need help

[@Liberty4Ever]

I've been binge watching Slant 3D videos for the last week and now I think I'm addicted. Is there a 12 step program or something?

[@WillPower311]

I really appreciate y'all , your channel and all that you do! I've learned and continue to learn a tremendous from your content!

[@denisw398]

Great job of getting people thinking of 3D printing as an enabler to better and more innovative designs. As an ex-engineer I find your material very educational for my own projects. I wish your print farm every success and thanks for sharing in this way.

[@slant3d]

Wow, thanks!

[@4LXK]

Will replace all squeching old door handles with this and magnets, thanks!

[@juliejones8785]

This is such a great series. Learning how to better design for 3D printing is such a different way of thinking.

[@framxframxx1868]

This makes me want to design things in a whole new way … 🎉

[@SHAD0WZOMBIE]

Best way to produce the bucket handle is a single aluminum extrusion, cut to sections. Alsmost no waste. Perfect every time.

[@davethetaswegian]

I only came across your channel recently, but I am finding it very insightful. Definitely making me rethink some of my 3D printed designs. Thanks.

[@GP3D_Designs]

A bucket grip (@ 0:28) can be continuously die extruded at a very low cost of production and sawed off on that very same line of extrusion. Edit: Dense foam filled-in extrusion, and/or empty contoured shape using other polymers.

[@slant3d]

Up front cost of the die. Minimum order Quantity. More material Used. Cannot change the design. Also cannot round the ends as is needed but we did not update the model in time for the video to be published. But fortuantely is is 3D Printed so the design can change at any time.

[@n0pc0de]

@slant3d to be honest though wouldn't the die extrusion process be hugely more efficient? as in meters per second of parts produced vs an hour per part for 3d printing?

[@DaveEtchells]

@@n0pc0de Definitely true, but the economics of it will come down to how big a run you’re looking at doing. His other examples literally couldn’t be done with other technologies (or would be uneconomic), but this one could indeed be extruded if you were making 10s of thousands of them. His other points are all valid too though, and I suspect if you were looking for quantities of 5k or less 3D printing would be the winner.

"Everyone has command strips in the house" I've never heard of command strips before this video. 🙈

[@BLECHHAUS]

Me too :-(

[@FreedomToRoam86]

@@thedolenorway if you go the Universal Dormitory and Apartment Store (Walmart) it is kind impossible not to know what they are. Of course I didn’t know they were all called Command Strips, just thought it was the ones I used

[@thedolenorway]

@FreedomToRoam86 I live in Norway. We don't have Walmart here.

[@Rudmin]

It would be pretty trivial to extrude the bucket handle from an extrusion die.

[@cbgslinger]

Think different, design different! Another outstanding video to broaden our horizons.

[@slant3d]

Glad you enjoyed it!

[@tonyharion9816]

You guys have been rocking on the latest videos!! Well done!!

[@slant3d]

Glad you like them!

[@chuckcharles5963]

I like the ideas but the grip in the beginning is somewhat of a bad example. While you are correct that it is difficult to injection mold or mill it is perfect for extrusion. The setup would be even cheaper that hardmilling a mold since you only have to edm a 2d template with minimal rake. But other than that great tips as always.

[@slant3d]

Partially true. But extrusion would not have the texture. There would fairly high minimum volumes. You of course have the up front cost of the die. And it would be heavier which would increase shipping costs and lend slightly to user fatigue if they have to use it for extended periods of time. And it could not be produced on demand and have the design changed at any time.

[@MilesLabrador]

This video is too good; I can't handle it!

[@slant3d]

Easily best comment we have had. Thanks for watching

[@HarveyFoFi]

I have the same exact tool box LOL. I am going to start making stuff for it. :)

[@MNCasaPro]

@13:15 regarding texture: could you start first layers with what amounts to an infill to create a texture on the downside of a printed part? Thanks

[@ZaxMan3D]

Hey As always awsome content. i was wondering if you have any tips on making a wall mount for a TV box? I have a model made but I'm not sure its the best way to go about it due to print angel.

[@andrevanrossum8408]

I really like your channel, because you see things from another angle. Thank you!

Best 3D print series on youtube. Keep em' coming, fam!

Appreciate that

[@jonathanlawley4863]

0:59. Do you actually have any background in injection molding? Shrink is ALWAYS a factor. While it is true that thick walls are not best practice because of sink marks, especially for some materials such as ABS, that does not mean that they are impossible. I've seen products thicker than yours injection molded. It comes down to material selection, injection/packing pressure, and cooling time in the mold. You produce good content and are definitely an enabler for the 3D printing hobby and small entrepreneurs. But please stop misrepresenting injection molding. I get it; the injection molding industry is your competition. So are some other industries/processes (rotomolding, blowmolding, metal stamping/forming), but your videos make it very clear that you view injection molding as your most influential/dangerous competitor. I'm a plastics manufacturing and design engineer. I've worked in additive, extrusion, injection molding, thermoforming, and flat-pack structures. I've designed for several other industries as well. 3D printing is not the holy grail, and I say that as one who was enamored with it years ago when I got my first printer in college.

[@sergemarlon]

I challenge you to build a set of rock climbing holds. I've been printing all sorts and installing them on my fence. The kids love it.

[@slant3d]

MakeAnything already did that

[@sergemarlon]

@@slant3d I Watched his videos, also I believe different creators so things differently. It seems your creativity would develop something different than him. Imagine if everyone who makes clinging holds today has that same mentality, "is already been done", what will get done then? I stand by my challenge. I would love to see another KZbin creator develop something as creative as rock climbing holds.

[@Marksman123771]

What is the texture on the outside that you're talking about?

[@slant3d]

Really enjoying this series 👍

[@slant3d]

Thanks

[@josephhurtado8113]

What you if filament are you using for the door handles?

[@kennethbeal]

Thank you! In the last minute, you were talking about how ten years ago we wouldn't be able to manufacture these -- and now, they are very sparse and hollow on the interior. Reminded me a great deal of learning atomic structures: first, everything is so dense; then, we learn that at the sub-atomic level, it's "mostly open spaces". Really neat, seeing our technology pattern our world.

[@GamesPlayer1337]

Your first part could be quite easily manufactured without 3d printing tho. You could theoretically just extrude it and then cut to length. Would be cheap and quick to manufacture. Otherwise very great video as always :)

[@slant3d]

Problem is: Up front cost of the die. Minimum order Quantity. More material Used. Cannot change the design. Also cannot round the ends as is needed but we did not update the model in time for the video to be published. But fortunately is is 3D Printed so the design can change at any time.

[@GamesPlayer1337]

@@slant3d All of those are valid points. But the cost of the die wouldnt be as expensive as its not needed to be very precise. The rounded edges are nice, but for such a product not needed honestly. I feel like both, 3D Printing and Extruding, has its up and downsides in this particular product and both are pretty viable in their own right in my opinion. But thats no critique on your idea and or video. It surely has really great upsides that this is 3D printed, as you said especially design changes are easy and quick. :)

[@pvp-mcprison29]

13:14 when you say "applied the texture to the outerside so it doesnt look like a printed part" what are you referring to, are you adding a pattern in CAD that effects the visual asthetic?

[@nombre652]

I personally used blender modifiers to do something similar and it visually eliminates layer lines and even the z seam completely, wich looks spectacular. There's also a configuration to do so in blender wich will make random movements all along x and y axis, but I haven't tried it since it makes it all around the piece and wasn't looking for that

[@pvp-mcprison29]

which modifiers mate?@@nombre652

[@Victor_2019]

Love the Video, could I use this product idea in my print farm?

[@TS_Mind_Swept]

It's funny how much you showed sticking these onto a fridge, because they just got a new full sized fridge at the place I work, and for whatever reason the thing doesn't have any front handles.. will be suggesting something like this for it

[@thailandretromods]

As a total "ugga booga" caveman who welds and hammers... This is glorious!!!! 😂❤😂❤

[@GGDiegoNeira]

I need your wisdom plisssss, I'm a complete noob on 3d printing, but I've been trying to get a retractable laser saber that can resist playing with it. If I print verticaly they are really fragyle but horizontal is a pain in the a... I love your content

[@VD-cc4hx]

1:30 could you use a hot wire to cut a block/dowel of plastic into that shape? i bet you could. you might need some robot to move the dowel while it cuts it with the wire. but you might have wasted material if the plastic arrives in a rectangle, then you shave it down into a dowel shape.

[@g.s.3389]

based on your experience, how many perimeters and which % of infill would you use for those handles?

[@slant3d]

Depends entirely on the specific handle. But most of these are fine with 2 perimeters and 10 percent.

[@B0A2]

The link to the files isn’t working for me, I am using the KZbin app so maybe it works on desktop?

[@darrennew8211]

I realized I needed to start putting dents in the parts I print that I intend to hot-glue together. Not mass-producing anything, but the glue needs somewhere to go.

[@braavosassassin]

When you say thick skin, are you referring to using more than 2 perimeters?

[@corneliuslucaverein3533]

You have severely times mentioned “a texture that doesn’t look 3D printed”. Could you elaborate what you are talking about? I could really make use of this technique or 3D modelling move.

[@saadqadeer7807]

You can add fuzzy skin texture in slicer, not sure about making it in Cad maybe some pattern can work.

For all of you that keep saying an extrusion would be easy… are any of you capable of doing extrusions at home?

your myminifactory link doesn't seem to work

[@slant3d]

Weird. We will take a look

[@minkwandering3561]

I notice you kept saying how thick you can make everything, without mentioning how thick you made anything.

[@TheRealFOSFOR]

I'm pretty sure all of these handles can be made by injection molding. You just need to cast them in a few parts and weld the parts together...

[@jasonhunt7382]

And that would be easier than printing it?

[@TheRealFOSFOR]

​@@jasonhunt7382 Claiming that it is 'impossible' or 'utilizing excessive material' in any other manner is inaccurate. Two half shells can be produced through injection molding and subsequently welded together, entirely automated within a large Chinese factory, ultimately reducing the cost of one part to a few pennies, as opposed to the 5-hour duration required for printing a single part.

[@gridleaf]

The link to your myminifactory page seems broken. KZbin seems to not like the space in the username.

[@ulamss5]

TIL injection moulding can't do big simple shapes.

[@McRootbeer]

How would you design a pen?

[@slant3d]

We'll see

[@air8536]

The parts ive printed with the highest quality have walls 2-3mm wide and are at least 15mm tall. Not sure how that would work out with the small parts of a pen Using a 0.2mm fdm printer or a resin printer would be better for that though

[@JaKlaro]

0:45 you could just extrude it. And then cut it. its just a extruded profile :)

[@JaKlaro]

I read another comment that says the same.. read the answere from you.

Dude it's not rocket science. Give part A a track or slot. Give part B a nub or something that slides in the slot. If you can't figure it out, find something that moves and take it apart
