Bluetooth Audio Board Case

I recently bought a Bluetooth audio board and wanted to use it. After a while I decided it would be the best to make a case for it so it will be protected while playing around with it.
I even aded some vent slits to the top and bottom case to prevent overheating, at least I thought it would become hot inside this case but it never happened so far. At least the slits are there should that ever happen. It even has a little cut out in the lid to allow the capacitor on this board to not get damaged when closing the lid.

It does fit with the following Bluetooth audio board: https://www.amazon.com/KNACRO-Wireless-Bluetooth-Receiver-Amplifier/dp/B071S2Z61V/ref=sr_1_3
(For German users like me it's this board: https://www.amazon.de/MagiDeal-Digital-Verstärker-Bluetooth-empfänger/dp/B076MG5BDR/ref=sr_1_20)

You may need to sand the inner part of the lid a little in case it doesn't fit. It was just a rough model of a case.

I thought I'd share this here and hope someone could use it as
