These are TPU mutes made to fit 4", 90mm, 3", 65mm, 2", and 45mm diameter guitar sound holes. They press into the different size sound holes as a collapsible mechanism.
I originally printed all separate mutes, but then figured out i could combine them all into one. So i did…out of Overture TPU 95a
Most guitar sound holes are 4" or 3" diameter, if theyre metric there's an in-between 90mm size
I also included files to fit different fretboard styles, dreadnaught's will usually extend to the sound hole.
There are also a 4" single, 90mm single, 3" single, and a 3" & 4" combo mute files for those without smaller guitars.
The author marked this model as their own original creation.
