Hi there!  This is my version of a wall mounted 12 Port Patch Panel.  There are two plates, one for the base, and one for the panel.  For the top part, my testing shows any type of plastic seems to work out well, however for the bottom I found PETG offers a little flex which is helpful for this piece.  If you print using another plastic, it may be worthwhile to increase the infill to 75-100%.

I have tried my best to pre-form the supports for you to reduce the defaults the slicer offers, and I cut the tolerances on the connecting pieces pretty close.  I hope you find a use for this one, thanks!
