This is a 3D-printable full-body case with a removable lid for a Mean Well RSP-320 series power supply (fits all models in the series, e.g. RSP-320-24 or RSP-320-12). The case will prevent direct contact with the metal body or terminals of the PSU making it safer to use. It has all the vent cutouts the PSU has as well as all the mounting holes. PETG or other material withstanding temperatures above 70 degrees Celcius is recommended for printing.
