A different type of pulley set.
These are photo etched and the pieces stack to give the pulley depth.
You could also cut a piece of round styrene or aluminum rod or tube as a spacer between the pulley faces.
Pulley face has 6 round holes plus a hole in the center.
There are enough pieces to make 6 pulleys.
All pulleys are the same diameter - .22" OD.
