This is a print ready chain hoist capable of 30lbs or more (30lbs is all I had on hand to test with). 8x16x4 Ball Bearings, #10 Ball Chain and 3 different M3 screws are required to make this function.

The system has a 3 stage reduction. They are as follows:
Drive 2 to Drive 1: 27:9 or 3:1
Final Drive to Drive 3: 27:9 or 3:1
Doubler Pulley: 2:1
For a total reduction of 18:1
Purpose of this thing: I was bored and had a few bearings sitting around so I decided to see how much I could lift using plastic.
