Description
I was experimenting with printable ball bearings. Then I had this thought, why not print the ball bearing recess right into the moving parts? This is the monstrosity that came out of SolidWorks. I call him Crazy Gear Face.
Instructions
1. Print one of each STL.
2. Place 4 BBs into the recess of the gear.
3. Being careful not to drop the BBs, place the Gear onto the face.
4. Align the BBs around the groove so that they hold the gear in place.
5. Align the dimple in the gear with the dimple in the face. This dimple will act as a hole that you can load more BBs into the bearing.
6. Pop 9 more BBs into the dimple-hole.
7. Repeat 2-6 for the other gear.

Hey, this is a really cool print piece!
I'd love to have the source, so I can modify it for different bearing sizes. In general its nice to upload source so people can do whatever they want! Not everyone has Solidworks so I typically also include STEP or IGES files, which import into most cad programs but are much easier to work with!
For now, I'm just printing the whole thing scaled up 33%, so it should fit my 6mm bearings if I did my math right, but source would really be great so I can keep the small size and use whatever bearings I want! :)

I made one :-)
Scaling it up 33%, as tlalexander here suggested, to fit 6mm softgun-BBs that i have. Well, the print turned out perfect, using BFB 3D-touch with 0.25mm layer thickness and clear PLA. But tolerances are a bit tight. my gears are forced against each other, and as for loading more BBs in through the grove.. i tried jamming one in with the back of a pen, but the BB actually shattered. Anyways, i've managed to get 7 BBs around in the large gear and 6 around in the smaller pinion. And though not exactly moving freely, they do turn around :-)
