Finally got the flash hider off my JG p90 to measure the threads and decided to make a suppressor/silencer in blender. I made three of them with 14mm negative threads so it will fit most airsoft guns. The sizes are 30x80mm, 38x80mm, and 38x120mm and I also made a threaded adapter to fit airsoft pistols. I have only tested it on the p90 and i'm planing to test it on other airsoft guns later. Print with no support and use standard print height 0.2mm. Tested the 38x120mm suppressor today and had some lower than normal shots. Upon checking the suppressor there was some wear from the airsoft bbs making contact with the suppressor. So i made a new version of the 38x120mm with a wider opening by about a couple of millimeters. The smaller 30x80mm did not have any problems. Update: Tried the adapter on a WE 1911 that had a threaded barrel with the orange tip pulled off. It didn't work due to size and further research revealed that the pistol threads are 11mm positive thread. Just posted the pistol adapter 11mm positive to 14mm negative. Working on flash hiders, when i get some good prints i will post them. Added a reinforced pistol adapter due to one of my friends easily breaking it. If it does break off in the pistol barrel it can easily be cut out with a hobby knife. I've also added a threaded spacer. Added new pistol adapter version 2 with better threads. I have printed it and the threads look better but have not tested it yet. Added 24mm positive thread versions to work with some ak47-74 types. Added a new suppressor 45mm x 240mm, due to size I had to make it in two parts.
