Sprite Bluetooth Speakers

Sprite is a speaker design from Paul Carmody. The design uses Dayton ND90 3-1/2" drivers. A few other components are required depending if you use the 8 ohm or 4 ohm version of the ND90. I used the Dayton Audio KAB-250v3 2x50W Class D Audio Amplifier Board with Bluetooth 4.0. Many other amplifiers could be used also. The print maxes-out the print area of a 300x300 bed, must be printed at a 45 degree angle to fit. I didn't use supports.
