Xiaomi 16-in-1 screwdriver knurled ring
I wanted the knurled ring from similar types of this screwdriver (LTT, etc.) that allowed one to quickly turn a screw once it is loosened.
Update: made the knurling coarser. It looked great in Fusion, but my printer (E3 V2, 0.4mm nozzle) could not produce that detail :D
