Hi
I will a) lett it print from a Company or b) get it printed by a Hacker space if I find one.
I dont know what te use for printer now.
In either case you will need to output the 3D model STL file from your CAD program, and they will do the rest. Shapeways,
dirty PCBs, your hackerspace, or others.
For something like the dirty PCBs SLA, they can basically print anything. But if its from a hackerspace (FDM), there are some limitations on to how you can design the part. If its a simple design I wouldn't worry about that right now though, it will probably be fine.
