Probably best printed with PETG or ABS if cabinet temperature is likely to be quite high. I made this because temperatures over 20˚C in the cabinet cause PLA to jam in the PTFE tube. No supports needed, 50% infill, 0.2mm layer height.
The bracket is designed for cheesehead screws (I used No. 8 x ½" self-tapping, which I think is M4x12 approx).
