I designed this box in OpenSCAD. I used heat inserted nuts to screw everything together. This is also the reason why you will find some holes in the bottom plate towers and the mounting block at the top part. I bought a cheap soldering iron and heated it up till 250°C to insert the nut inside the PLA.https://nl.aliexpress.com/item/100pcs-lot-M3-L-D-4-Through-hole-brass-insert-nut-knurled-nuts-for-injection-moulding/32806163767.html?spm=2114.13010708.0.0.3a994c4dDbx6YD
The complete box is bolted together with M3 screws with a flat head.https://nl.aliexpress.com/item/250pc-set-M3-Cap-Button-Flat-Head-A2-Stainless-Steel-Hex-Socket-Screws-Bolt-With-Hex/32775208136.html?spm=2114.13010708.0.0.3a994c4dZrD8EY
I made this code generic which means everything is recalculated if you change some parameters. (even the gaps inside the walls). Furthermore I used 3D tool to check every important parameter of the compete box.https://www.3d-tool.com/en_free-viewer-download.htm
