DIY Bluetooth Audio Receiver (case for VHM-314)

thingiverse

This is a cost-effective and convenient way to connect your phone with older audio systems that only have a wired connection, especially in cars. It also provides high-quality music without interference, unlike many cheap devices available in stores. To make it, you'll need: 1. A VHM-314 Bluetooth Audio Receiver module (available on eBay or Aliexpress for a few bucks) 2. A 5V power source (a standard USB charger will do) 3. AUX and microUSB cables to connect with the audio system and power source Assembly is incredibly easy; just place the module in the lower part of the case and secure it with the upper case. Remember to apply some double-sided tape (about 1mm thick) between the inner edges of the upper case and the module to ensure a snug fit. I recommend leaving a small gap for possible variations in module thickness and 3D printer accuracy. You can also attach a small piece of transparent tape on the LED hole from the inside of the upper case to protect the module from dirt.
