This is remix of CalculatedCosplay's Black box.
The grooves for the screws are glued at the level of the cover with screws. It can be a little difficult, besides the glue should be sticky enough to fix the grooves well. Cyanocrylate or epoxy will do.
I took the screws from my assembly kit from Ender 3. These are screws m4x16. I chose them because they're black and required length.
I also mirrored some parts, so the model is a little bit different from the original.
