Hanging Mainboard Case for Ender 3

thingiverse

I required a case that perfectly fits the stock Ender 3 mainboard to suspend under my enclosure. So I utilized the fantastic design of [Ender 3 External Electronics Case](https://www.thingiverse.com/thing:3631413) as a starting point. I also wanted it to be easily detachable from the enclosure by sliding it in and out of the drawer-like bracket so that I can remove the printer from the enclosure without having to unscrew the case or disconnect the wires. I designed this to slide into the bracket in an orientation for the USB port and SD card slot to face outwards. However, when I installed it I realized that I couldn't do this because the bed heater cable was too short. So, as you can see in the pictures, I installed it at the rear of the enclosure sideways. This works perfectly fine, as the box can still slide in from under the enclosure, and I use an SD card extender to reach the edge of the enclosure. The screws that I used were M3x8. Be cautious when screwing through the tabs on the lid into the box. If the screw is not aligned with the hole in the box correctly it will push the tab out until it breaks. There are two versions of the box available. One has more vents than the other. The lid and bracket will work with both.
