A bench top power supply in the style of this video but with a different design based around a Acer Veriton FSP250-50GLV 250W PSU (pictured) could easily be adapted to a TFX or Flex ATX psu, FreeCAD file and step files included for easy conversion.

Front panel is modular so that you can change up the modules to your liking

Recommended to print in PET-G but PLA could work, about 700g of filament total.
