I made this box for my Adimlab Gantry-S printer and the MKS Robin Lite board that it ships with, but it will also be useful for a variety of printers and boards. This is designed to fit all the electronics (Pi, buck converters, controller) in one enclosure instead of separate enclosures. Note that the wiring will need to be carefully tie strapped and routed to fit properly.

This box will fit a variety of control boards:
MKS Robin Lite which is in the pics
MKS Gen L
MKS Nano
SKR 1.3 / 1.4
SKR Mini and SKR Mini E3

This enclosure is too small for large boards like a duet or an SKR Pro. It is also too small for the Adimlab Gantry black and the white board versions, but it will fit the MKS Gen L board that is in the Adimlab Gantry Pro and many other printers.

This box is made to mount two DC/DC buck converters to power a temperature-controlled PWM fan controller and the Raspberry Pi for example. The fan is a 120mm x 15mm, 4-wire PWM fan. Future plans call for some different fan configurations. Let me know if you would like a particular combination. I can also add mount points for MOSFETS and things like that.

For hardware, use 3mm self-tapping screws for the boards and the lid. Use 3mm screws and nuts for the fan.

9/9/2020: Added a parts list/wiring diagram for buck converters.
9/4/2020: Added a new bottom file for the MKS Gen L so the USB will line up better.
8/31/2020: Added a new bottom file for the SKR 1.3 and 1.4. Moved the board mount point over to add more clearance for the power wires. Moved the USB and SD cards to their optimum positions. This is the version I have printed and pictured. Will check compatibility with the Gen L board when I get a chance. Renamed files to help clarify.
8/30/2020: Added a new bottom file for the MKS Robin Nano.
6/11/2020: Added the text file instructions for the temperature-controlled fan module.
5/26/2020: Added two new bottom sections that fit the SKR Mini E3 board. This is for the Pi 3B+ and the Pi 4B. This board will mount with either the SD/USB on the left or the right side of the box (see pictures). Also added, two new lids with 80mm and dual 80mm fans.
5/2/2020: Added a new bottom section that fits the Raspberry Pi 4B.
4/16/2020: Added a diagram of the control boards and their positions in the box.
4/14/2020: Updated the lid fan hole positions and reuploaded models
