This project includes a comprehensive code for my power supply enclosure. The necessary components were sourced from AliExpress, including power supplies, switches, fans, and DC cables.

This is the reason for the presence of holes in the bottom plate, tower, and mounting block at the top part. To insert the nuts into the PLA, a cheap soldering iron was heated up to 250°C: 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 enclosure is held together with M3 screws featuring 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 The code is designed to be generic, recalculating all parameters if any changes are made, including the gaps within the walls. Additionally, 3D tools were used to verify every critical parameter of the complete enclosure: https://www.3d-tool.com/en_free-viewer-download.htm
