Summary

This is nothing more than https://www.thingiverse.com/thing:4948912 zconelli design but with added screw holes to allow hardware mounting to a wall.

I imported teh file to FreeCAD which I stink at, exported it as a Collada file, imported THAT to Sketchup, made my changes since I don't have the expensive version of sketchup I had to export again as DAE, import back to FreeCAD and then back out as STL...

Sliced in Cura using Ender 3 profile, printed on a Voxelab Aquila and it fit my Iris keypad perfectly.
