My 3D Printed Kinematic Paint Mixer

[@UncleJessy]

Already ordered my kit! Cant wait. Absolutely love this project!

[@MarkRhodesMaker]

Thanks man! Look forward to seeing what you do with it dude!

[@MrAsj567]

Owesome! I just got a 3D printer with my son and he has been printing little novelties that I told him he should paint. I dug out my old hobby paints that have been sitting for centuries. Now I have something useful to print and use. Thank You!!!

[@MarkRhodesMaker]

That is awesome, welcome to the 3D printer party! I actually have some free files on printables for hobby paint racks.

My dog is diabetic and requires insulin shots twice a day. I've been told by different resources that I should vigorously shake the insulin vial before drawing it into the syringe or to roll it vigorously. You've just solved the problem and saved me a bunch of time to develop an insulin shaker. Weeeeee. The vial is a little smaller than the paints you use but I think this will do the trick in mixing his insulin. Thanks so much for a wonderful ideal. I found you via HackSpace magazine.

[@MarkRhodesMaker]

That is awesome Marie! I still have a couple of kits left on Etsy

[@mariemeyer2885]

@@MarkRhodesMaker As it happens I have a 3D printer (Prusa MK3s) and have started to print you files. I like to send you a tip for your work any suggestions on how I can do that? Thanks again for taking the time to share.

[@mariemeyer2885]

@@MarkRhodesMaker Well, I went ahead and ordered from your Etsy cause I could always use another for my airbrush paints. ;-)

[@MarkRhodesMaker]

@@mariemeyer2885 thanks Marie! I’ll get it in the post ASAP 😊

[@michaelmbutler]

What I have read is that rolling is much preferable to shaking. So you should probably find a way to run the shaker really slowly. But I’m not a doctor and this is not medical advice; and I’m not a veterinarian and this is not veterinary advice. Cheers!

[@radsy5821]

I was considering subscribing until your rant about craft herpes. Then I immediately subscribed. Thanks, printing now, looks like a well engineered solution.

Currently in the learning phase of setting up a workshop for micro controller based projects as well as building and painting D&D Terrain and Mini's. Been looking for a silent way to mix paints and I believe I have found it. Could probably add more cylinders or even rubber band or velcro strap a few bottles on the outside to mix several at the same time.

[@phalkoni]

Brilliant Job Mark and well demonstrated

[@louis177]

You got me chomping at the bit for the bigger one. Would love one that could handle resin bottles and cans of spraypaint. :D Might even look into modding this myself. Solid design!

[@MarkRhodesMaker]

Literally in the finishing phase of a bigger one! It'll be going on my Etsy within a couple months. It handles 1L resin bottles, rattle cans, etc.

Glad you like it!

[@michaelmbutler]

Googly eyes make it utterly next-level. I salute you, sir.

[@Mojoptix]

That bottle-holding rubber-band contraption is genius ! As a potential upgrade, you could maybe design a gizmo to collect all the excess glitter. Static electricity works really well... so maybe add a cat feeding mechanism ?

[@MarkRhodesMaker]

I plan to never ever use glitter again, so hopefully it wont be a problem. Fingers crossed... !

[@Aelinnia]

I'm late to the party here, but just came across this and have to say: Ingenious! Great research, design, and execution, Mark. I love that you didn't just make a cool mixer, you made a gold standard mixer. Go to extreme lengths or go home! I don't have access to a 3D printer, so if you ever decide to make more kits, I would rush to purchase one! Thanks for sharing all this. Really nice video too.

[@SpunkeysModelShop]

Very cool paint mixer you made.

[@JamsAlx]

Mesmerising to watch it mix. Really great print will be printing it next.

[@MarkRhodesMaker]

AWESOME! I'd love to see it!

[@patprop74]

It's a cool design, It is exactly what 3d printing should be! Well done.

[@MarkRhodesMaker]

Thank you very much! And I agree 100%

im so glad i found your design so i figured id show you some love and subscribe i noticed you only have one design on printables you need to do more your a beast ... thanks man from all the way in INDIANA USA

[@juddery]

I came for the paint shaker, but subscribed for the humour. Excellent work on the design by the way. Very cool indeed.

[@MarkRhodesMaker]

Thank you! Really appreciate it :)

[@IMChrisThom]

Definitely like this and will print it. I would like to have a hand crank version though.

[@MarkRhodesMaker]

I've actually been meaning to add a hand cranked version!

[@andyb7754]

Very nice and interesting video. Thank you.

[@ThysaniaAg]

Liked the video, the mixing tool, and you! 😂

[@MojoMountainMan]

This is a really awesome design... Now you need to ramp it up so that it mixes all 20 bottles at once

Thanks Cat!

[@ulaB]

Now that is an interesting mixing mechanism.

[@MarkRhodesMaker]

Thanks! I can stare at it working for ages!

[@AndrewKendall-PortPics]

I'd be curious about one large enough for a spray can.

[@MarkRhodesMaker]

I actually have one that large, but I’m working to make it more reliable 😂

[@AndrewKendall-PortPics]

@@MarkRhodesMaker let me know when you have got it working!

[@WayneMcCormick]

I've finally printed this but I modified it to use ABEC bearings (the ones typically found in spinners) for the pivot end. I did that because I thought it was binding there, but even after than the rotation of the drum isn't smooth, it stalls at one part of the movement. Maybe my motor doesn't have enough torque?

[@MarkRhodesMaker]

Hi Wayne, possibly! Did you use the motor I recommended? I thought about using bearings for the next version, might give these a try!

[@WayneMcCormick]

@@MarkRhodesMaker As close as I could. It looks the similar, runs on 12v, but only 50rpm. www.amazon.ca/gp/product/B07D294GS7/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

[@MarkRhodesMaker]

@@WayneMcCormick then it should have more torque, seems very odd! I’ve shipped quite a few completed kits and haven’t had any reports of issues. Might be the motor, might be the print. Have you lubed all the contact points that don’t have bearings?

[@MarkRhodesMaker]

@@WayneMcCormick interesting…. Seems pretty close. Mine are slightly larger so might be more powerful , but you’d think with the gear reduction it wouldn’t matter. Greased all the joints? I am testing a replacement motor, that you should be able to order anywhere

[@bipolarchemist]

This will be great for mixing my glow-in-the-dark alcohol inks. Well, suspensions really as the particles settle pretty quickly and at quite annoying to shake back into a mostly homogeneous mixture. Now to figure out a way to run 8 off a single motor...

[@MarkRhodesMaker]

Yes it would! Running 8 might be challenging, unless you've got a big motor with way more torque available 😂

[@RV_There_Yet]

I know you love playing with glitter. I was waiting with baited breath for it to pop open ... 😂 Seriously Mark ... Awesome project and results. I can already think of multiple uses.

[@MarkRhodesMaker]

Fking glitter. Thanks man!

[@ThePudge1976]

Wow, impressive beyond belief. The best looking and seemingly most effective! What diameter is the motor housing? Smallest motor I can find in UK is 37mm . Great work Mark.

[@MarkRhodesMaker]

Check out Aliexpress. You should be able to find some smaller options there.

[@m.muzinski7842]

Good one!

[@coregeek]

My next print for sure!

[@MarkRhodesMaker]

Heck yeah! Hopefully you can find a similar motor over in the states!

[@WilliamTythas]

could this be scaled up to work for paint rattle Cans

[@bots2beasts]

This might be useful for small molds for making miniature copies and ensuring the resin gets to all parts of the mold. At least THAT's what I'm gonna try doing with it.

[@MarkRhodesMaker]

I've been working on a bigger one and that's one of the use cases I had in mind. A simpler automated replacement for a rotocasting rig.

[@bots2beasts]

@@MarkRhodesMaker Well if you make a decent hand cranked one, PLEASE let me know so I can download it and save some time. lol

[@shadowops62]

Just found this. Cool! Just another reason to get a 3D printer, lol!

[@FigoNOVA]

I love this, a version with longer arms for larger buckets would be cool

[@MarkRhodesMaker]

It's on the way! I'm already working on a bigger version for Resin bottles. However larger is more difficult to engineer with plastic 😬

[@FigoNOVA]

@@MarkRhodesMaker Maybe you could use a small turbine (I saw these on the "Golden Ratio Turbine" vid from Integza) I don't know a lot about this stuff but that's the smallest amount of filament I've seen agitate such a large volume of liquid.

[@MarkRhodesMaker]

Very nice project. Problem is the Prusa link isn’t working.

[@MarkRhodesMaker]

Thanks Wayne! Fixed!

[@joconnor5241]

Any suggestions for motor alternative for US purchase?

[@MarkRhodesMaker]

Unsure sorry. If you can find a 70rpm geared DC motor that might do the trick!

[@billbat1]

Great Video, thanks for sharing, I'm looking for something that can work with large resin bottles 960 ml for 3D printing. Do you think this will scale up to this size?

[@ahmadmaskaleh2175]

would this be scalable like to take a litre bottle of resin

[@MarkRhodesMaker]

That was the plan, and I managed a prototype, but it needs a lot of work 😊

[@benlastname8520]

Where's the follow up of the bigger version?? :)

[@shizki]

Hey Mark, the jaycar site you linked for the parts says they are going to be closed for a few months. Is there any chance you might have some alternatives for the motor and parts for those of us in the US? Thanks for making the amazing mixer and sharing with us.

[@MarkRhodesMaker]

Hey Michael, the next version I was hoping to do with a simple 3v hobby motor that you can find anywhere. So stay tuned! Otherwise if you can find a geared DC motor that runs at 70rpm that would be perfect.

Mark, I tried to find your kit for the kinetic mixer and much to my chagrin it isn’t available. Have you stopped selling the kits? Thanks in advance.

[@MarkRhodesMaker]

Hey Ronald, Try over at my Etsy. www.etsy.com/au/listing/1688288142/inverse-kinematic-mixer-kit-effortless

Great project, I love it! Is there a minimum speed on it? I'm not a mech e but I can see where scaling this up to mix slightly heavier bottles will be tricky given what you said on the Edge of Tech about the necessary tolerances. Any way to use algorithms or tinyML to monitor and tweak the motor currents to offset flex in the frame, changing center of gravity or am I overcomplicating things again? XD

[@MarkRhodesMaker]

Thanks! Re speed would be easy to control with a PWM controller. Haven’t looked at TinyML, but I would expect that it would given enough time and controllable variables find a best RPM and width, or even a modulated RPM for efficiency. Cool idea!

[@cpfenn]

can I use a 100 rpm 12 V motor?

[@Ryxxi_makes]

have u tried using Nylon locknuts instead of 2 standard nuts ? Any chance I could buy just the non 3D printed parts ? am In Australia as well !
