A low polly nailgun I made for one of my games.

nailgun_vX.X.zip contains DAE files for the mesh, and two sound files for the sound effects.

nailgun_godot_drag_and_drop_vX.X.zip contains godot files for the nailgun. Just unzip and drop the file in the root of your godot project. Call .shoot() on the nailgun object to play the shoot animation and sound.
