milwaukee sausage plunger caulking gun barrel

thingiverse

I had a Milwaukee plunger caulking gun and the inner red plunger wars out and wraps around the sausage inside the barrel, so i made my own with tight tolerances to defeat against that. try it out, print it base down, i don't know how it ended up on its side, i made a few before they fit nice 100% infill i guess so it don't break, you'll want supports to make it bottom side down i guess see photo. Red is original, yellow is print
