Simple Airsoft Suppressor

thingiverse

This is a simple airsoft mock suppressor I modeled for a 14mm CCW threaded barrel. I specifically designed it with a 35mm outer diameter so that it would fit recessed inside the rail I'm using. The overall length is 130mm. I also designed a baffle (not sure if it makes a difference). This design is meant to be used with 5 baffles. Update 4/29: The first print was mostly successful! The 14mm CCW thread fits nice and tight on the barrel. The baffles slide ride in. However, I had a really hard time getting the cap threads to engage. I have revised the cap threads by reducing the thread diameter 0.2mm and adding a small fillet to the thread. I am printing the revised cap now. Update #2 4/29: I was able to get the threads to engage after revising the end cap, but still too tight to continue threading. I have reduced the thread diameter another 0.1mm. I am printing that cap now. Update #3 4/29: After third rendition of cap, I was able to thread it all the way into the body with substantial effort. I also found that I left too much space length-wise inside the body for the baffles. I have revised the body internal threads by increasing the thread's minor diameter by 0.2mm. I also increased the overall length of the plug by 2.0mm. I needed a second one anyway, so I am currently printing another full set with these newest revisions. Update #4 4/30: Success! The latest print came out very well, and I was able to assembly without tools. I have found that the tops of the baffles need to be sanded down slightly to remove any surface variations, in order for the cap to close flush. Leave a comment if you would like to see any changes. FYI, it doesn't suppress the airsoft gun at all. Not functional, but looks cool.
