This is a remix of the excellent "Enclosure for KNACRO TPA3116" by designer timskloss. https://www.thingiverse.com/thing:3439466 The amplifier in question can be found on AliExpress: https://www.aliexpress.com/item/32842016553.html Many others share a similar footprint, all based on the TPA3116 chip. Some have Bluetooth capabilities while others do not. As a side note, the current model as I purchased it uses the newer TPA3116d2, features Bluetooth 5.0, and sounds incredibly good. In fact, it truly blew me away with its quality, which is impressive considering its price of under $20. The changes made to the original design are: - The top and bottom have been modified for passive cooling purposes by adding ventilation. - The front panel text has been increased in size, featuring taller letters with a font that doesn't fall off at the middle. This modification accommodates larger nozzles (printed here with 0.6mm). - The letters are now cut through all the way to create a backlit effect if there was more light inside. - The front panel groove has been moved 4mm further back, allowing for maximum potentiometer stick out so the knobs can be turned fully without obstruction. - Small cutouts have been added under the potentiometers for alignment tabs. The modifications were made directly to the original designer's polygon files, which means no CAD files are available for download. 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.
