Designed to house and make look better than the original amp comes.
Here it is:
S350HS TPA3251 Bluetooth Power Amplifier Board with Subwoofer 2.1 Channel 220W×2+350W - https://www.amazon.com/dp/B0CHF6MML7?psc=1&ref=ppx_yo2ov_dt_b_product_details
Added front, top, rear and total rig pics. Turned out pretty good.
For 1 extruder printers use the files with "WithText" in the file name
For 2 extruder printers use the AmpHousing-Bottom with AmpHousing-Bottom-text.stl and merge them. Do same for AmpHousing-Top and AmpHousing-Top-txt.stl

Logo credits - Thank You these turned out excellent!
