FN-BC04 Mount

This is a tray to reverse-mount the FN-BC04 audio board from electronics123.com such that you can access the volume control potentiometer through a closed housing. Use this tray as a template to drill the 4 outside mounting holes in your housing, plus the 3mm hole next to the label to mark where to make a 1/4" or larger adjustment hole.
Use M3 x 6mm+ bolts to attach the FN-BC04 board to this mounting tray, and 6-32 or equivalent to mount to whatever housing you are using.
Cutouts in the tray are so that you can read where the wires are going for troubleshooting.
