Bluetooth Speaker 2.0

thingiverse

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