Gear Spinner.

These don't spin as well as the standard bearing spinners - the gears produce more friction and slow everything down, they're cool though! Fascinating to watch spin, creates an awesome optical illusion pattern.

Assembles by press fit, no bolts/screws required.
Requires FIVE 608 bearings - the center gear uses 2 bearings.

Print the following:
2x Frame
3x 608 Gears
1x Frame Gear

Once printed, you'll be able to see how it goes together - easy

Support required for frames (I will redesign soon to get rid of this support) and for the "frame gear".
