Xbox 360 PSU holder

thingiverse

This accessory securely fits your Xbox 360 PSU onto the printer's 20mm-wide extrusions. Two versions are available - one prevents sliding from the bottom, and you can print two for dual restraint. Alternatively, there's a version that allows for sliding movement. Please trim off just the rubber feet without damaging the hard plastic. My printed version utilized a 0.3mm layer height and 10% infill.
