3D model description

Update 6/25/2019 Added Lids by shadowpanther
Update 6/20/2019 Added a fixed STL for the Pi Box by shadowpanther.

This is a remix of originally by fiercedeitylink.

I adjusted it to fit the Ender 3 Pro, added places to mount another buck converter and a 4 channel relay board. It should also fit a MKS Gen L.

I have 1 buck converter set to 5v for the Pi and relay board, another set to 12v for the lights. The relays control power to the SKR, mosfet, hotend lights and gantry lights. The Pi is running Octoprint with the Enclosure plugin which allows control of the relays over GPIO. I needed to remove the jumper on the relay board to power the relays with 5v and not fry the Pi.

The box hangs down about 20mm below the base of the frame so you will need some feet. I used the ones included with the original model and added some rubber pads under them for more vibration dampening.

These are the links to the parts I installed.
