I like the look of Armourist's version of an ATX PSU. But I wanted to use heat set inserts instead of nuts. Also fuses and special components should be added. So I started with modifying his design but ended with designing my own version of it. After publishing my make on his page I got asked for my files. So here they are. Be aware: I hadn't time to clean up these files for publication. When I do have some sparetime, I will recreate this whole project with OnShape and add some improvements and a full description. So this is actually “work in progress” and at the current state I just provide these files as is. 

Things to improve:

• replace the nuts in the frame rails of the PSU with heat set inserts. (These parts have been taken over from Armourist's model)
• Push the handle forward and attach a stop to keep the power supply straight when carried
• use car fuses instead of the cylindrical ones to save space
• add description and BOM
