40mm gost BDSM scent filter

thingiverse

I was looking for a gas mask filter you could open and put whatever you want into it to force the gas mask wearer to smell the contents. It took some sanding to clean up some of the modeling mistakes I made when I modified it and the parts fit a bit loosely, but after sanding and panting it with several layers of paint it fit well enough. May want to figure out how to add some threads to screw the two halves together in the future so that's not an issue. I also had a bit of obstruction in a few of the air holes on the bottom so you probably want to get in there with a needle file or something to make sure all those holes are unobstructed. I got them clear with a couple hex keys since I didn't have any needle files
