Airsoft blaster type tracer housing

This is a blaster style 14mm CCW suppressor/silencer/flashguard designed to house the much cheaper Acetech Brighter C tracer units. 

You can optionally take a Brighter C unit out of its casing and use the same 3 screws to mount it into the base of this version, then simply screw on either of the body types.  You can leave out the tracer unit if you just want the empty shell, as the tracer does not form a structural part of it.  The complete design should then screw onto a standard 14mm CCW thread.

I use 0.12mm layers for the thread parts as it's quite a fine pitched thread, and 0.20mm for the rest for speed.
