35mm + 16mm Sprocket Roller Package (1/4" d-shaft bore)

2 models:
-35mm + 16mm film rolling sprocket
-16mm film rolling sprocket

both with a 1/4" d shaft axel bore

* note the sprocket teeth on the larger roller have been tapered at a 23° angle - this has been done to avoid having to sand down drooping layers as the PLA printer I'm using can't print smooth right angles unsupported
