Here is a clean and versatile box in which to put your ramps controller. Includes a solid top that fit's into the top of the box. My thought is to have either one fan blowing in and the other out, or a fan in and a vent out. There are recesses for 3 nuts on the bottom, you will need 3x 3mm by 23/24mm screws to hold down the ramps This was a pain to print. Took about 9 hours. I'm fairly new so your results may vary. I used a single layer raft and 3mm brim, 2.5mm spacing on 45 degree support structures. The holes came out really well, and all the dimensions are correct for the 3mm screws. You could probably get away with taking the wall size down a bit.
