I'm still new to the whole CAD scene, using FreeCAD at the moment as it's sufficient for my beginner skills. I don't have a 3D printer yet, but I'm in the market, as it were...
I'm about to get my "printers license" at a local 3D printer shop so I'll be able to test my designs soon-ish. I am creating all this stuff so I'll have something to print as soon as I get the opportunity.
I also have a deviantart page http://spaceman-spliff.deviantart.com/ , which I keep mostly for online picture storage, and an instructable account http://www.instructables.com/member/Spaceman-Spliff/
