About this model

This thing generates pulleys for round belts (and ropes). You create any size pulley, with or without a hub, for round belts of any size. You can have any number of belts Your pulley can have zero to four mounting screws, with or without nut traps. The axel hole can be any size. You can create smooth wheels (no belts) or with any number of grooves. Using 1 or more round belts or O-rings creates a wheel with a tire. You may want to check out my closely related thing for creating round belt pulleys. ( UPDATE 1-- July 31, 2018 -- Posted updated file that corrects an error in calculating the pulley diameter. (Squashed a gremlin that had been creating a pulley diameter that was ½ the belt diameter too small.)
