Instructions
The layers are sandwiched together and are designed to be held together by a pair of screws and nuts which go through the 2 wholes to either side of the shaft.
Layers (to be modified to fit your material thickness)
+ simple spacer
+ nut trap
+ simple spacer
+ pulley teeth
+ simple spacer
Update: The nut trap can now be turned off as can the washer-like layers and there are options to render each layer seperately if you want to use different materials.
I'm also working on preset Configurations for Mendel parts as I need them. Currently I only have a preset config for the motor drive pulleys (drive-pulley-3off - it's attached) although it shouldn't be to hard to use that as a basis for the driven pullies given you just scale the shaft up to M8 and set then number of teeth to 21.
