BTT HDMI7 mount adapter for Neptune 3/4 Pro Plus Max

I really love the simplistic look of TacticalBeanie's vertical case, also with the 7" screen, it's a bit too big to mount horizontally… so with very little experience I cobbled an already existing Neptune 3 display bracket together with the bracket for the vertical case. Sorry it's ugly. (Mesh isn't properly optimized for printing, but it prints fine.)

You can get the vertical BTT HDMI7 case from here.

If you're like me running everything off of an rPi 4, this is what worked for me to get my screen and touch input properly rotated:
RPi 4: 
add display_hdmi_rotate=3 to your boot config
don't forget to comment out dtoverlay=vc4-kms-v3d
add Option "TransformationMatrix" "0 -1 1 1 0 0 0 0 1" to the InputClass section of the "touchscreen" InputClass inside /usr/share/X11/xorg.conf.d/40-libinput.conf

Edit: 

Dec 2nd: I want to come back to this soon and clean it up a lot. This was my first ever attempt at a remix so apologies for the rough look.  

Dec 2nd an hour later: Here I am, I updated it real quick. Should work fine now.
