This is an extension arm for the Alesis Forge Electronic Drum Set Module.
I found that the Module was always right in the way of my High Hat, so this arm will move it up and out of the way. it rotates around both axis to wherever you want.

The large clamp diameter is 37.5mm
it requires 2x M4 Nuts and Bolts.
the Tube end of the arm is 38.5mm diameter and fits snugly inside the Module clamp on the back side.

No supports needed
0.3mm layer height
The 3mf file holds all my slicer settings in Prusa
