Retro Bluetooth Speaker

I designed this speaker as a bit of fun. I originally designed it for 4 inch speakers but I got a deal on Amazon for some open box Pioneer 130mm speakers. I designed it for use with the DollaTek Amplifer listed below which was very cheap and actually works really well and is perfect for this project. With some modification, this could be used with a Raspberry Pi and a DigiAmp+ or a HiFiBerry with Volumio, but the cheap amp is much more cost effective and user friendly if you only want Bluetooth connectivity.

I had some bad vibration where the amp is at first, but I cured this by putting some insulation tape on the bottom of the amp. For the 3D printed parts, I found that low infill works best, so used 5%. I printed the frame upside down and the cutout face down using supports for both. Nothing else needs supports. There is a small amount of soldering required and some super gluing. The only electronics knowledge you need is to know the difference between positive and negative.
