Athough there is a lot a choice for the same purpose, none were like I wanted. So I made my own. I printed mine in glow in the dark PLA, printed quite well.
I did a version for an M4 countersunk screw, and another one with the best low profil nail hole I could do. The Dot is held in place by the USB cable.
There is holes all around for the loudspeakers.
.stp, .ipt, and *.stl included, have fun ;-).
Easy print, very little deburing needed and no modification required.
