I have access to programs like maya and zbrush and was thinking of using those. Had a look at this website: https://www.3dhubs.com/ but i got nothing to get a quote on yet. Was planning on printing an redesigned aluminium glock hop chamber because the current standard designs are fucking atrocious.
@Samurai on here does his own 3D work and is possibly worth approaching.
CAD was £210 and 24 items 4 inches long with a few angles and holes(nothing complicated) cost me £240. The CAD drawing is the issue, most things can be made for under £20 as long as they are not massive!
