Why did I make it?
I made this because I had recently watched a video by Tom Builds Stuff (I think that's the name of the channel) and was inspired to make my own attempt at a simple version of the cycloidal drive I saw in the video. This however is only part of the reason why I made it, I also made it because there was a challenge going on in Atlantis(created by Hack Club) to make a pocket-sized thingy and get a free sticker for it.
How does it work?
To be honest, I don't know much about cycloidal drives, but I wanted to make an attempt at it, so I'll try my best to explain it. The way this works is the input shaft is slightly misaligned which allows the gear to move around the shafts and reducing the speed of the input. The bearings on the side allow the gear to move around the input shaft without being fixed to it.
Assembly:
Printing/slicing:
Download all of the files under the "Printing" folder
Import all the files into your preferred slicer
Auto-orient all of the models to the plate
Space all models if necessary to make sure no model is in collision with another
Under supports select organic tree supports
Select slice and then send the sliced file to your printer
Assembling printed parts:
Take the gear part of the cycloidal drive and insert a ball bearing into the middle indent
Repeat Step 1. and insert the rest of the ball bearings into the middle indent
Insert the drive base into the gear like so
Insert the input piece into the top of the drive base and gear
