thingiverse

This is simple pulley for paracord. You can use it to create a zipline. Not intended for load. Just use 2x M3 x 18 bolts and 2x lock nuts. It can be set on a rope after the rope is tied. Print both parts twice to create one pulley. After print, heat plates (with lighter) below pullies and bend them to form the shape.
