electric longboard motor pulley for propeller mount, HTD-5m

This is a pulley for an electric longboard that i have built. It is made for the HTD-5M profile and a 15-16mm wide belt.
inner diameter is 10.2mm to fit snuggly on a propeller mount for the sk3 149 Kv motors. (included in the box with the motor, but probably works good for other motors mounts too.)

EDIT: If you can, use nylon. I've used PLA, it works good for some 20-30 km or so, but I think nylon would be the way to go.
