Raspberry 3 A+ Case for Prusa i3 MK3/S with camera cable slot.

thingiverse

This is a remix of the original design of Jonlynn. I took his designed and added a slot for the Pi Camera and a perpendicular arm that fits the Prusa i3 Frame. You will need 2x M3x10mm screws to attach the case to the frame. I highly recommend using this M screw nuts set from Aliexpress for a lot of different projects. https://www.aliexpress.com/item/480pcs-New-Hex-Socket-Screws-M2-M3-M4-Stainless-Steel-Head-Cap-Screw-Nut-Set-With/32816555979.html So far, Octopi is running great on the Raspberry Pi 3A+. I connected the Raspi to the printer using a short USB cable that I bought in Aliexpress. https://www.aliexpress.com/item/Anti-interference-high-quality-short-20cm-A-Male-to-B-Male-USB2-0-Printer-Cable-Line/32809052856.html I recommend buying the original Raspberry power supply, 5V 2.5A. I tried using other PSU's and had a power alert on Octopi every time. If you modify the cable for the power, be sure to use an 18AWG cable, not less. https://www.aliexpress.com/item/Official-Raspberry-Pi-Universal-Power-Supply-Interchangeable-heads/32806827449.html
