Enclosure for MKS Robin Nano V3.1

This is an electronics enclosure for a custom 3d printer I am building. It houses two different control boards. In my case it will be a MKS Robin Nano Ver3.1 and Raspberry Pi 4.

The boards sit on a panel which can be slided in and out; and and each panel is fixed with two M3 bolts to the mainframe. This provides more flexibility during assembly especially for cable bundles.

There will be a second iteration for the following improvements

- Change M5 bolts to M3 for panels; and use countersunk instead of buttonhead (aesthetics) - Use spring-lock mechanism to fix the boards in place instead of M3 bolts For durability reasons I used heat inserts to fix the screen, the electronics boards, rubber feet and the fan. You are welcome to change it to nuts & bolts. In addition the M5 nuts on each panel shall be a tight-fit. Please make sure to check the holes for your M5 nuts.

All parts are printed with PLA+ and without any supports. The final model will be printed with PETG. Other than the printed parts you will need below items for assembly
