Pulley
thingiverse
This is a pulley for ropes and cables. The model comes together with the corresponding SCAD file so you can adjust all parameters (pulley diameter, central hole size, thickness of pulley, rope diameter, ...) on your needs. Or you can just open it in the Thingiverse Customizer and specify the parameters there. The pulley with the default settings has a total diameter of 50mm, the hole in the centre is 22mm wide (so that a bearing of the very common type 608 fits in) and the diameter of the rope or cable should be about 3mm. I have not tried printing the model yet.
