Thing-O-Hoist
thingiverse
This print-ready chain hoist can lift 30lbs or more, featuring 8x16x4 ball bearings and #10 ball chain. Assemble it using three different M3 screws with a total reduction of 18:1 (3:1 for drive stages and 2:1 for the doubler pulley). The creator built it out of boredom, using printed components including solid Drive 3 gears to ensure proper torque transmission. Follow instructions to assemble the hoist; test with a light input on Drive 1 to check functionality. Use #10 continuous ball chain from Rollease for optimal performance.
