Wallmount bracket for 19" devices

I recently bought a switch and need to screw it to my wall. so I designed a nice bracket to do so. It should fit to all 19" devices with 4x M3 screws each side. Print with 3-6walls (at least 2mm) and Gyroid 30% infill. I (as always) use PET-G to get stiffness, PLA might break if you tighten the wall screws (use more walls with PLA!)

Of course, you may swivel the bracket by 90 degr if needed!
