This suppressor I designed to fit my SCW-9 SD2 Pro GBB airsoft gun, it has an unusual 18mm CW thread on the bottom end, but you can use the customizer and make it a standard 14CCW if you want to use it on a more traditional mount, the length is also adjustable if you want a shorter or longer version.  Inside the top of the center core is also space for an Acetech Brighter C tracer module.  Personally I chose the center core to be eSun Metal PLA Silver, and the exterior and end caps to be eSUN PLA+ black, but I can imagine other colour combinations working.

I printed everything in 0.12mm layers to give a fine finish.

I strongly recommend you use the customizer and download the thread tester to try out on your printer, it prints a small screw on cap that you can use to test out if the ‘slop’ value is right for your setup before you spend the very many hours printing the main pieces.

Assembly is simple, screw the bottom cap onto the core module, slide the mesh over the core, optionally insert your tracer module into the top (it should stand a few mm proud), then screw on the top cap to hold everything together.  Then screw onto your barrel and use as usual.
