Yea, I just opened the dxf in estlcam. With a 1/16th inch(1.5mm-ish) endmill you can cut the nut traps, but it’s close. You could use wingnuts instead, that way if you have too much slop, the wings will catch on the panel and still not spin freely. Something like this probably should be laser cut. I’d be afraid of messing up those traps.
