Programmable Music Box

This is a programmable music box based around an Adafruit Feather M0 microcontroller with a Music Maker FeatherWing. When the lid of the box is opened, the microcontroller is enabled, and starts playing an MP3 file while driving a continuously rotating servo motor to rotate a figurine.

All printed parts can be printed without support material. Silk PLA or PETG seems to work well.

In addition to the 3D-printed, the music box requires the following:
- Adafruit Feather M0 Express (add female headers, pointing upward)
- Adafruit Music Maker FeatherWing w/ Amp (add male headers pointed downward)
- Micro SD card
- FS90R Micro Servo
- KW4-3Z-3 microswitch
- 503035 500mAh lithium ion polymer battery
- Adafruit 3W 4 Ohm speaker (product 4445 or 3351) - cut the connector off the 3351
- assorted wires and header pins

The servo runs off the Feather, with the following connections:
- brown wire to GND
- red wire to 3.3V
- orange wire to pin 1 (aka A11, aka TX)
