Water faucet handle

This is an handle I designed for the water faucet I use at work, it can work with many municipal and residential faucets.

The center hole is a 8.3mm square as that was the best size for my use, I included the fusion360 file (.f3d) if you need to modify the dimensions.

PRINT THIS IN A STRONG MATERIAL, PLA IS TOO WEAK. (I used PETG and it is working perfectly)

Other note: make sure the outside diameter of the cylinder (16mm) isn't too big for your faucet, I had to reprint it because I made it too big at first.
