This is a case to fit any of the Dayton KAB cases found on Parts Express. This particular amp is the KAB-230v2, but I believe all the hole patterns are the same. This has holes for two speaker wire outputs, power cable, the on/off switch, and the aux line. I cannot promise it will fit the volume pot, as I don't have one to try. I uploaded the sldprt file if you would like to modify it.

This version has two tabs to surface mount it, but am working on a version with a lid and mounting holes through the base. I will update that when I'm finished.

I put 9mm grommets on the holes that the speaker wire and power cable go through. The holes are undersized, you will need to drill them out to whatever spec you need.

This was printed with cabron fill pla, but any material will work. I hit it with some matte black spray paint because I didn't like the difference in surface finish between the build plate face and the sides.
