Prusa Mini - Back cover with USB

I want to print for my Mini a front USB dock and a back cover for LCD. I'd like so much the Display Usb Mod by Joe but i don't have an orange PETG filament... only black. Also i'd like so much the design of Displaybox Cover by 4nthonylin and in this case black PETG is perfect for the scope. So... why do not mix it all? This is my version, a mix of these two project in one. The only constraint was making something printable without any support and that is perfect integrate with the original line of the mini. For this i've decided to split the project in part that can be glued with a cyanoacrilate glue. All parts have joints that help to keep every single part in position during the gluing. All the 4 screw M3x10 need to be replaced with the slightly longer M3x12. This is the cable compatible with the dock: https://www.amazon.it/gp/product/B01K48IRXO/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
