Had bad neighbors that constantly bang and stupidly loud music, recorder would just about pick it up but not good enough, brought one of these and put it on low volume only when the nuisance happened.

Built this so i can have it closer to the wall, the holes are for the screws to fix it to the wall.

This is only for the like of what i have with neighbors and need to collect the evidence, this is not to spy on people and i don't condone that.

Just print how you like really, mine was on a ender 3 pro, 20% fill. size is set.
