40mm NATO to GOST adapter

This thing disappeared from this site and I happened to have the origanal file. Ocording to the files this was made by Shakenbake 28, so here it is the NATO 40mm to GOST adapter. Adapter goes in mask and NATO filter goes into adapter, simple and easy. The second file is there for if the adapter threads is too small. I recommend you print the second one first.


Update 10/24/19: Improved the alternative adapter for more printer support.
