One piece suppressor for plinking in the garden quietly with you 22LR rifle or threaded 22 gun.
Ideally to be printed out of PLA+ or HPLA. or any polymer that can withstand heat well.
To be printed vertically, slowly for good layer adhesion.
When in use always make sure it is well seated. Wear safety googles.
The sound suppression is movie quiet. Nobody will hear a thing.unless you shoot on steel :)
I have used tough PLA and it works well.
Also a drop of weak loctite on the thread makes sure that the tube stays in place.
