Cases kit for Geekpi 7inch Portable Screen V2 (52Pi EP-0186) with attached Pi3b+ or Pi4b

I carelessly printed and struggled to fit the display case that I have remixed here, not noticing until I had ripped the OSD rocker switch off, that my display was not the one for which that case was designed.

I therefore had to model this case for myself, but I did take advantage of the design-thinking that went into the original case.

I already had my pi3b+ in the case that I have remixed here.  I find it particularly well designed for my needs.  The best answer for me was to just tailor it to stand alone as a lid (it normally nests into a bottom half, so some walls were missing.) 

I tried printing both of these cases in PLA.  Unfortunately, the tabs I added to the pi case are far too stiff and brittle in PLA and printing it flat on the bed makes the tabs particularly easy to snap off, when taking the case on and off.   I have instead printed it successfully in PETG, which is more flexible and forgiving, and which has a bit stronger layer adhesion.

Maybe someone out there has a much better idea for installing the lid?

The Fusion 360 model timeline is a "hot mess", and I found I had drawn a mirror image of what I meant to do in the first sketch, so I “cheated” and just mirrored that sketch before extruding the solid model.

I have also included a model of the assembled kit, including a simulation of the pi3b+ PCB, to help anyone who decides to try to remix this kit.

CAUTION:  Because of the orientation of the Ethernet connector and its close proximity to the Geeekpi case, one needs to use tweezers to release the lock on the connector to disconnect it from the pi.
