3D Printed Stackable PLANETARY GEARBOX - Unlimited Gear Ratio

If u going to build this, then please send me a picture of the INSTAGRAM, I really love to see how people build my designs.
This gearbox has practical use in the real world for sure, and probably even in RC vehicles. Probably u see this gearbox in this channel more.

When you print with PETG, be sure to increase the infill. Using different infill patterns will also yield better results too.

Ok bro, you got me. Liked and subscribed with notifications plus a little engagement here for the algorithm.

You're very talented. Not only in mechanical engineering, but you're a master of 3D printing! People who haven't 3D printed before just think you click print and out comes a perfect object. They don't understand bed leveling, offsets, rafts, infill, elephant foot, supports, overhang, bed and nozzle temperature, nozzle cooling, extrusion size and feed rates, etc, etc...there is so much that goes into getting a perfect print and you make that part look easy.

An awesome video like always. Printing the sun gear perpendicular to the force direction will greatly increase strength. What I mean is print the sun gear in two parts (length-wise, perpendicular to the gear teeth). The plastic is failing due to the torsional force being in the same direction as the print layers. The parts will be a lot stronger.

Nice gearbox! Needs an output stage with output bearings and a overload clutch. (maybe some mounting holes too?) The output bearings are to support overhanging loads, and the overload clutch will make the gear-box bomb proof by slipping before anything breaks. I've made overload clutches both with spring loaded friction clutches and detent mechanisms.

You... You made a functional modular planetary gearbox?? That's incredible! Really, well done! I can't wait to see what you use it in next :D

I can't wait to see this channel once metal 3d printing becomes affordable to you. All of a sudden, what previously would be considered toys would become real alternatives to commercial parts and assemblies. Make sure to save every design. With even minimal automation, I can see how this might turn into a business - selling assemblies that now are durable enough to use for hobbyists and eventually professionals.

I enjoyed the video, but whats even more enjoyable, is your accent! MAN it is such fun to listen to your words :D No joke, really mean it! Been watching a couple of your videos now ;)

This is really fantastic work. I think it is sincerely admirable that you made the files to print this free to download. A true maker.

[pietrom]

i think that a nice idea would be to print with increasing stage thickness, so the gears are thicker when more torque is needed and thinner when they spin faster to reduce drag and gearbox size, if i will prints these i think i will try, being in need of pretty high reductions

[mozkitolife]

Very clever. Great work. You should know by now by intuition that those load-bearing parts require much more than 20% infill.

[maverickstclare]

good idea but why not 100% infill for the "coupler"?

[bjornwiegel]

Nice gearbox but why didn't you use a design where you could access the bearings inner ring from both sides? In this way you could have tightened up the mounting screws in the planet gear carrier more decent and without paying too much attention to the mounting torque. This would also make your design more robust and lead to a more precise movement of the planet gears...

Archimedes once said “give me a lever long enough, and a fulcrum to weigh it on, and I shall move the world”. With this gear box you could turn the earth with enough stages 😎

Great design and work!

[JjMn]

Super cool!
A modular gearbox is even cooler!
You can use this for so many projects!

[ARandomTroll]

you should look into helical gears. would make this much more stable and reduce friction, since the gears are self retaining.

What lubrication was used for plastic on plastic connection?

[blackscorpi]

Can I have the stl file for the part on the wood ?

2:53 "Do just a little Wiggle Wiggle" xD Best part that make my day :D

[legen_dary]

Congratulations! You made a desktop winch! Seriously, I could use this overhead in my shop.

[WhiteDragon]

Gearboxes usually look like disasters of incomprehensible moving parts, but this is a very smart way of keeping this all tidy!
