This model is based on the original PSU cover for the MK3S for the Delta PSU ( https://github.com/prusa3d/Original-Prusa-i3/blob/MK3S/Printed-Parts/STEP/psu-cover-DELTA.step ).
This allows a DC-DC converter to be mounted out of the way on a MK3s. Designed for DC-DC converters such as https://www.amazon.com/BINZET-Converter-Regulator-Regulated-Transformer/dp/B00J3MHRNO/ .
