Hi there, I've been playing with NopSCADlib in my attempt to create a 1U Rack Server for OrangePi Zero, because it supplies a lot of things I need and I don't want to re-create, like PSUs. https://github.com/MerryKombo/3DDesign/blob/0bbe0034a2ea322eedfd18370d174a9c26cd8b0d/assets/Server%20Rack/1U/modules/1URack.scad The thing is I just can't understand how the PSUs are defined. I'd like to use the ones I own, so I try to define them in the same style as the ones that already exist: https://github.com/nophead/NopSCADlib/blob/master/vitamins/psus.scad . The S_300_12 for example is commented on, but I just can't wrap my head around it... I tried to define my S_96_12 there https://github.com/MerryKombo/3DDesign/blob/rear_modules/assets/Server%20Rack/1U/modules/power-module/power-supply-dimensions.scad but I got it all wrong, as the side holes are just messed up... I just don't know what the coordinates refer to. I would love to contribute if ever I could manage to understand how the PSUs definitions work. Could anyone try to explain to me how this works? Best wishes, -- Bruno Verachten

Hi Bruno, You would be better raising an issue on NopSCADlib rather than asking here. The screw positions are defined relative to the centre of the face they are on. The two holes at 79.5 are exactly on the edge as the side is 159mm long and one clashes with the sloping part. [image: image.png] Where should they be?

Chris, The screws should be closer to the center, I don't have the PSU with me, but if the holes have to be defined in relation to the center, I will measure and modify the definition in my file. It's not a bug, it's just a problem with the chair-keyboard interface. I will try and keep you posted. Thanks for your help. Bruno
