Ender 3 Pro Mainboard + Raspberry Pi B+ Case

Hello, after building the ikea lack enclosure I wanted to get the ender 3 pro mainboard and my raspberry pi b+ out of the enclosure - so I needed a case which I can screw under the ikea lack table.

My idea was to keep it still good to open, so I implemented the bolts and make a lid which connects the case. So first you would need to screw in the two lids and than you can screw the case with the 5 bolts.

It should fit the "creality ender 3 pro 4.2.7 mainboard" (and actually all other creality boards cause the screw holes are at the same position), an raspberry pi b+ and a 40mm standard stock fan.

I took the already very good design by drewzh and optimized it a bit. (other ventilation holes, mounting etc.) Also I took the great knurling bolt design from here:
