this is a faceplate that allows you to install your AC Infinity fan controller onto a standard network rack. made out of 3 pieces (one centre faceplate, and two identical vented "rack-ears", it utilizes m5 hardware to secure together, though 10-24/32 from your local hardware store works in a pinch.

printing:

i've been able to print this on ender 3v2, successfully with default (minimal/no) supports and just a brim, on versions sliced with both cura and prusa.
