Ender 3 SKR Mini E3 all in one rear electronics case (dynamic sizing) with 2 x 40mm fans
thingiverse
A remix of https://www.thingiverse.com/thing:3945794 The designer uploaded scad files which was awesome. I have updated the scad files to my liking, now the boxes/lids are dynamically resizable by changing the variables in the scad file, using OpenSCAD. The top buck convertor is set at 5V and powers the Pi 3B. The lower buck convertor is set to 12V to run the 2 x 40mm Noctua NF-A4x10 fans. The board is SKR Mini E3 but the spacings should fit other boards. The relay is 30A to switch power to the Ender mainboard. I added a BME280 temperature sensor to the Pi3B and placed it next to the SKR board, maximum temps I am getting are in 30-35C range (so pretty good). The right fan blow in across the stepper heatsinks (contrary to the photo), and the left fan pulls air out of the case.
