Banana Gun and Knife. Made both by combining parts in MeshMixer. Knife is solid, the scope on the banana gun has a void behind one of the eyepieces. Didn't affect me when I printed, so I didn't care enough to fix it, but it's good to know.
Knife is a large file size because I had to increase the triangle count to get the banana and blade to properly combine.
Part of my Halloween costume - I'm going to be an banana who is also an assassin.
