Prusa i3 MK3 EINSY Raspberry Zero With Door and USB HUB

thingiverse

I remixed the EINSY Case with door from https://www.thingiverse.com/thing:2734810. It was a good solution for the installation of a Raspberry Pi Zero W. But after a while I saw some minor flaws and the possibility to hide camera cables. I started the remix with the door: It was annoying that you had to open the RPI door first to get to the screw to open the EINSY door. So I added a hole for direct access. Next I changed the case. I made it 3cm longer, so you can hide the folded webcam cable inside and fix it with cable ties. That gives you a much cleaner look. I made a hole in the back for a USB connector so you can also tie in the USB adaptor cable you need for the webcam. The webcam can then be connected from behind. In a third stage you can use this 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 It can also be cable tied within and gives you one port behind and three ports downward. Maybe it is possble to use more than one webcam and switch between them in Octoprint? We will see.. The last change was the cable insert from above. I never liked the original design. For some time I used https://www.thingiverse.com/thing:2696342. It works good, but looks as if it was designed for another printer. The original cable insert is also complicated to print due to the small overhanging ramp. So I enlarged the ramp and made a fitting plug for the other side. This design will help against premature wear of the nylon and the cables. The cable is now fixed with 2 cable ties instead of one. I found it uncool to fix the cable with 3 ties on the extruder and only one flimsy tie on the case.
