This is a remix of the excellent "Enclosure for KNACRO TPA3116" by designer timskloss.

This is the amplifier on AliExpress:

There are many that share the same footprint - all based on the TPA3116. Some with Bluetooth some without. As a side note, the current (Jan 2020) model as I bought it, uses the newer TPA3116d2, has Bluetooth 5.0 and sounds incredible. Like, truly blew me away how good it sounds. The fact that it's under $20 is a bonus :-).
Anyway

The changes are:

• Top and bottom are vented to help passive cooling
• Front panel words and font are taller with middles that don't fall out. This helps with larger nozzles (printed here with 0.6mm).
• The letters are also cut through all the way (backlit, kinda if there was more light inside).
• Front panel groove sits 4mm further back, meaning the potentiometer halfnuts are on the outside clamping the face panel. This allows max potentiometer stick out so the knobs can be on all the way.
• There are small cutouts under the potentiometers for the alignment tabs.

I just modified the original designer's polygon files, so no CAD files available.

From the original designer:
Use #4 x 3/8" round head screws to mount the board, and #4 x 1/2" flat head screws to mount the top cover.
