LEGO Technic Gears

Three fridge magnets that use some STLs I found online.

I adapted the axles so they could accept neodymium magnets so they stick to my fridge.

1. Print the axles with black filament.
2. Glue 8mm diameter by 3mm thick magnets into the axles.
3. Print the gears with grey filament.
4. Align and insert the gears onto the axles.
5. Stick magnets to your fridge.
6. Have fun turning the gears everyone time you walk past your fridge.
