I'm taking Industrial Design (think architecture but we design everything but buildings) and so we do a lot of stuff and learn a lot involving manufacturing. Recently had a friend tell me about this site:
go here
and thought it was really interesting. I know we cant get them to make recievers or slides or anything since even if they would, they are located in the states, but I was just considering my M3 shorty tri nozzle problem and if someone could get the design (I suck with 3D modeling programs on my own and we aernt taught how to use em till next year) we could start ordering steel/aluminum CNC machined tri nozzels, that or any number of other parts like extra strong mech boxes, custom scope/light/laser/etc. mounts, or anything else that someone needs custom made.
I know there are some people with access to CNC machines on this forum, me included starting next year, but its not so easy to get a lot of parts made if it isnt someones personally owned machine, this company says they will do anywhere from 1 to 1 000 000.
Just a thought, throwing it out there.
