Bluetooth Speaker 2.0

myminifactory

This is my second created bluetooth speaker. This speaker will replace our old radio at work. I made it without batteries this time and sounds pretty good. All the red parts are printed with Ninjaflex for an air-tight enclosure. The printer settings are 0.2, 10% to 15% infill, and three perimeters. The body and speaker parts require support. For color change, you can modify your gcode files on this site: https://www.prusaprinters.org/color-print/ I have heated up the brass knurls with a soldering iron. They slide right into the sockets. Be sure they are straight.
