Banjo Mute

This mute uses 2x M4 bolts and nuts. I used 10mm, but 12mm long ones would probably be better.

The holes in the mute base are undersized - thread the bolts through. The knobs (https://www.thingiverse.com/thing:4667839) need to be scaled 52% for M4 nuts. Again - this is undersized - use a bolt to pull/press fit the nut into the knobs.

The mute sounds ok. It's not as good as a commercial one I have, but it's not bad. I printed at 100% infill - mass helps dampen the sound.
