Aplifier Housing TPA3116D2 Mono

Housing for the 100W Bluetooth 5.1 TPA3116D2 Mono Bt Audio Power Amplifier (link at bottom).

The design is pretty simplistic, the amp slides in from behind. The two holes are for the volume knob and the AUX port. The openings in the back are for the power supply, the speaker wires and the USB port. The holes for mounting the backplate are ment for heated inserts M2.5x4x4 AB011 (link at Bottom), the backplate can be screwed with M2.5x4 or M2.5x6 zylinderhead bolts.

I uploaded two designs one with a nice texured front for better looks and one with a flat front for easier printing, you can choose yourself.

For a better look, I decided to not add extra holes at the top for screwing in the speaker cables. You have to screw in the cable, bevore sliding the aplifier in the housing and screwing the backplate shut. But you can also add holes in the slicer or just drill threw the thing.
