Prusa i3 MK3 EINSY Raspberry Zero With Door and USB HUB

I remixed the EINSY Case with door from https://www.thingiverse.com/thing:2734810, which was a great solution for installing a Raspberry Pi Zero W. However, I soon discovered some minor flaws and a need to hide camera cables. First, I modified the door by adding a hole for direct access to the screw that opens the EINSY door. This eliminated the need to open the RPI door first. Next, I lengthened the case by 3cm, which allowed me to hide the folded webcam cable inside and secure it with cable ties, resulting in a much cleaner look. I also added a hole in the back for a USB connector, enabling me to tie in the USB adaptor cable needed for the webcam. This allows the webcam to be connected from behind. To expand connectivity options, I utilized an inexpensive USB Hub: Makerspot 4-Port Micro USB Hub OTG (https://www.amazon.de/gp/product/B075ZKJ76L/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1). This hub can be cable tied within and provides one port behind and three ports downward. I wonder if it's possible to use multiple webcams and switch between them in Octoprint – we'll see. Finally, I redesigned the cable insert from above, which I never liked. Instead of using https://www.thingiverse.com/thing:2696342, which works well but looks like it was designed for another printer, I created a new design with an enlarged ramp and a fitting plug on the other side. This design helps prevent premature wear of the nylon and cables. I secured the cable with two ties instead of one, as I found it unacceptable to fix the cable with three ties on the extruder and only one flimsy tie on the case.
