Bevel Gear Fidget

This is a set of bevel gears I designed to resemble the main gears of a differential. I liked to see the meshing action and decided to make the gears rotate smoothly using bearings left over from spinners.

This project requires 4 x 608zz bearings. (8mm ID x 22mm OD x 7mm H)

You need to insert the bearings in to each bevel gear all the way to the bottom. This will allow sufficient clearance between the gears to spin freely, without binding. Then just screw each bearing down to the cruciform.

To combine two of the finished Bevel Gear Fidgets together, print two extra screws and the "combiner". It's best to assemble the combiners and two cruciforms together with screws before adding the bevel gears.

Please post your makes!
