Raspberry Pi cover for Octoprint

I created this Raspberry Pi cover with Octoprint + Octodash software installed. Raspberry 3B+ and 4 -inch touch display "Waveshare SK16340" is used.
The rear part is printed from PLA, the front frame is PETG for stronger screws of the screws (tighten the screws only lightly !!). The main part is printed with the rear surface on the pad, the support only in the holes on the screws.
I used M3x15 mm - 2pcs, M3x8 mm - 10pcs. The M3x15 mm screws are for fastening the frame on the top, the other screws are for Raspberry Pi and the remaining parts. To attach the rear support I got into the intermediate piece of the M3 threaded inserts. This part is glued to the main part of the cover. I apologize for the imperfect English.
