Gikfun Mini Solderable Breadboard Mount

I am wiring an interlock board for our makerspace's K40 laser cutter, and I used a Gikfun Mini Solderable Breadboard to do it. However, I needed a way to mount the device in the laser with the corners supported, as the holes are in the middle of the board and induce weeble-wobble (technical term) if you're pressing on it.

I am using the plastic uber-velcro to mount mine, but you could also add holes if you want. I have included an .stl of my design and an .f3d file from Fusion 360 in case you want to modify it.

The mounting holes in the support columns are 2.4 mm. You can tap the plastic with 3 mm screws or use a #4 screw to attach.
