Raspberry Pi and 7" screen case - with mounting arm for 2020 extrusion

This is a case design for a 7" touchscreen panel and a raspberry pi 3, it also incorporates a mounting system to interface with aluminium 2020 extrusion corner brackets.

The design of the case and bracing system is all entirely my work. The articulated arms, bolts and nuts are inspired from the articulated lamp thing. The 2020 extrusion mount is designed to plug into the 2020 corner mount things.
I had to rebuild both the 2020 extrusion corner (and extend the design) and the articulated arm to meet my requirements and allow me to easily edit them in sketchup.
Limitation: This was designed to print on the Prusa Mini, the Top and Base pieces only just fit on the bed and will kick prusaslicer warnings when sliced.
The parts are designed to use as minimal supports as possible but do require support enforcers in some places (hinge, base, brace), I've included the 3mf files with supports.
I've found that printing with a brim helps keep the edges crisp - the Top and base halfs will require a brim of no more than 3mm to allow them to fit on the mini build plate.
I've included the parts as individual stls and whole platters to allow you to pick and choose how you want to print them.
