I needed a functional "case" for my printers electronic parts, so I designed this thing. It provides space for the following parts:

1x Arduino Mega 2560 R3
1x RAMPS 1.4
1x MOSFET module for heated bed
4x WAGO 221-415 for connecting 5 V and 12 V devices easily
1x Potentiometer for fan control
1x 120 mm fan

To work on your electronic parts you can remove 3 bolts of the fan, rotate it 180° counterclockwise and secure it with 1 bolt (like shown in one of the photos).

The mounting frame has 4 small bridges which allow you to zip tie cables onto it.

I've printed it with 5 horizontal and 3 vertical perimeters, 20 % infill at 0.2 mm layer height. All the parts are easy to print without support structures.

The WAGO 221 Mounts by joochung were integrated into my design.

Hope you enjoy it!

Dimensions: 150 x 120 x 80 mm

4x M3 bolt 10 mm
4x M3 bolt ?? mm (depends on the thickness of your fan)
8x M3 nut
4x M4 bolt ?? mm (depends on where you want to place it)
4x M4 nut
4x WAGO 221-415 (optional)
1x Potentiometer for fan control (optional)
