Roller chain V2.0

This is a redesign from V1. the support of pinion, is better and pinions are more beautiful.
You need :
- 10 M3 nuts
- 10 M3 x 10 screw.

I never make this one but you can imagine with the picture of the V1.

This is a simple and useless roller chain made only with laser cutting.
This is made with 3mm MDF.
The center distance is 17mm.
Center of the outside chain link is square.
Center of the inside chain link is round.

You need to sand the pinion in the thickness to catch the chain
