Simple Pulley (Simple Machines)

So we are studying simple machines at school with my third graders and I thought about designing my own on Fusion 360 and printing it. I recommend using PETG instead of PLA if you want to lift heavier loads.
Just print each piece once. File called "Support 2" is the only one that must be printed twice. No need for supports.
Layer: 0.2
Supports: No
Infill: 50% or above (the more, the stronger)
Perimeters: 4 (0.8mm)
Once printed and glued, just use a string with a hook to lift the load and a string or a hook to fix it on a higher position.
Please, post your make if you print it!
