I bought a lot of a bazillion little speakers on eBay and needed a mount for them.This is a simple ring mount to hold the speaker. Use it on another project to add a simple mount.This probably will not fit your speaker. Tweak the openscad parameters to suit your device.cylIr is the radius of the speaker cylHole is the opening of the mount holdingRimH is the thickness of the retaining ring holding the speaker inafter getting something that fit my speaker, I then tweaked the tabOffset to moving the retaining bumps towards or away from the center until the speaker was held in tightly.
