This one was a request from the wife. A quick and simple little way to mount your JBL Flip or other favorite, round, bluetooth-enabled portable speaker. It maintains easy access to ports and buttons on the back and is simple to take the speaker off of. We have it mounted in the kitchen to save some precious counter space. You might notice I covered mine in something - it is just some adhesive-backed suede I got a roll of from amazon. It makes the interfacing surfaces between the speakers and the PLA I printed this in get along a little nicer in my mind, but it will certainly work fine without it.
The hole for the screw to go through in this model is 5.4mm, but the parametric Fusion 360 design files are included for easy remixing to fit your needs.
If you hang some up, post your make so I can see!
