Snapmaker J1 Rear Raspberry Pi 3B+ Mount

This mount allows you to attach a Raspberry Pi to the rear of the Snapmaker J1 without drilling new holes. 

The mounting bracket consists of two pieces which are supposed to be screwed together with two M3x5mm countersunk screws. You can also just glue these pieces together instead.

Then you just need to undo the two screws which holds the bowden tubes on the rear, slide the mount up and tighten the existing screws again.

Since the Raspberry Pi just attaches with some dovetails, you could also use this mount to attach other things to the back of the printer.

This mount works really well with the camera mod I uploaded and a short 15cm CSI cable.

I installed a 5V 3A DCDC converter inside the printer with a USB-C socket on the rear of the printer to automatically power the Raspberry Pi whenever the printer is turned on. Since I couldn't find any angled USB-C to angled Micro-USB cable with the right length, I decided to hook up the power directly to the 5V and GND pin on the GPIO header. Compared to the picture I later turned the USB-C socket by 90 degree.

The case of the Raspberry Pi 3B+ itself is based on someone elses design, but with many modifications. Unfortunately I couldn't find the original model anymore.
