3D Printed Stackable PLANETARY GEARBOX - Unlimited Gear Ratio

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

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

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.

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.

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.

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.

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

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

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

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!

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 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

Fascinating, your prints were almost hollow in the first round and yet still managed to pull up 20kg. If they manage to make the plastic bond as strong as injection molding, this would be a great way of saving lots of materials.

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 ;)

the design looks really professional

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

You should print the gears as separate pieces then the shaft (click together after print). If you do this you can print the shaft with the layers along the length and it will be much stronger to shear forces.

This is great design I was searching for, it inspires me to create something similar in my own projects. Thank you!

WOW! this project is very focused. The water pump one was impressive but only has some application. This has TONS of applications in other projects! If you had a way to bypass individual stages, you could make a variable gearbox

Great work. I'll try it as soon as I get more acquinted to my first 3D printer
