This is an openscad script to generate a pulley for strings and ropes. It uses a 608 ZZ bearing (the cheapest and most common ones, used for skateboards and rollers, about $1-2 on ebay).
With the source, you can tweak most of the properties, or use another kind of bearings.
The groove cover, attachment leg and top housing are optional.
I use these to lift bags of bird seed in my garage, out of reach of mices!
The pulley is to be screwed or nailed to a support on its own axis. However, the optional top cover makes it possible to hang it. The last picture show how I reinforced one that lifted about 50Kg.
