DIY drill battery radio

thingiverse

It's still work in progress. Radio module can go only to 70% (still loud) of volume before it stop be able to drive chosen speakers. There is no battery low voltage protection. M2 screws are hustle to use and its easier to glue nuts firs before assembly. I made my speaker with ports for each speaker chamber, but it sound better witch ports covered so I added side panel without ports.
