About this 3D model

I have several used ATX power supplies, harvested from old computers. These PS's are really powerfull yet rarely used outside a computer. So I purchased some step-down units and terminal boards from Banggood, and made me a fully manageble Lab power supply. The enclosure uses the thread from the screws already there. I also added the option for a 40x40mm fan to keep things cool.
