Gear for Playskool Busy Gears toy

This is a replacement gear for the Playskool Busy Gears toy.

Designed to pretty much the correct specs, but my printer (DaVinci) makes circles that are a little bit wobbly, so I had to sand and acetone the inside a bit to get it to spin freely on the peg.

Edit: there is now a remix which comes off the printer with an appropriately sized hole and does not need sanding: https://www.thingiverse.com/thing:5479534
