Chain and Gear

This chain is optimized for easy 3D printing, requiring no supports or difficult to print parts.

It is made of 2 parts, a plate with M3 holes, and a one with the rollers pre-attached.

You need 3 flat plates for every 1 roller plate. to make a link.

This design requires M3 x 20mm bolts, with nyloc nuts to secure the links together.

Also included is a 12 tooth pulley with an 5MM bore hole, and with one optimized for a stepper motor shaft.

Printed with 0.2mm layer height, 15% infill (they're small so doesn't get a chance to do much infill).
