3 Wheel Pulley Block
thingiverse
I made two of these to make a block and tackle for pulling up my kids power wheel up against the wall in my garage. No estimate on the max load yet but that likely depends on the material used and infill percent and will likely degrade over time. You will need: Steel Rod 8mm diameter and 25mm in length. M3 hardware to combine the pulley halves. 608Z ball bearings for each wheel.
