Nice! How much did that set you back? Also, have you looked into the possibilities of making rail covers and grips?
what printer have you got? been tempted by one as have few genres of use for it and can bluff my way through autocad. but so many manufacturers of them finding it hard to determine whats good and suitable for home use
I'd look into the UV activated 3D printing systems if I were you http://www.popularmechanics.com/technology/a14586/carbon3d-3d-printer-resin/
