The file 'Bike Lift Pulley 3D Printer Model' is (stl,skp) file type, size is 1.2MB.
I needed a pulley to lift bikes to the top of a shed to get them out of the way. I used standard skateboard bearings and 8mm bolts. Print on the side to make the holes stronger. I use 3mm bolts to hold the wheel hook to the bottom sheaves. I just looped a length of line to hook the wheel. Not sure of max weight.
