Gear Spinner Keychain

My take on a fidget spinner keychain. Designed in Fusion360 and printed in 3D Fuel Pro PLA on my MK3S.

There are 3 body options:
"Body" uses M3 Brass Heat Set Inserts
"Body Without Inserts" does not use M3 Brass Heat Set Inserts
"Body Without Inserts And Hanger" does not use M3 Brass Heat Set Insets and I eliminated the keychain hanger part.

If you use "Body", you'll need 2 M3 Brass Heat Set Inserts, 2 Skateboard Bearings and 2 M3 x 8mm Socket Head Cap Screws.

If you use "Body Without Inserts" or "Body Without Inserts And Hanger", you'll need 2 Skateboard Bearings and 2 M3 x 8mm Socket Head Cap Screws.

Print instructions

I usually print these in 3D Fuel Pro PLA.
15% infill is fine because the gears will automatically print in 100% due to their dimensions.
.15mm layer height is a great "Goldilocks" resolution.
No support necessary.
I design in Imperial (Majestic) Units. If you aren't using the latest PrusaSlicer, you will probably have to adjust scale to 2540% because 25.4mm is equal to 1".
