I must say that I am thrilled by the Gadgeteer project. I have worked with microcontrollers and assorted hardware from 1988 until recently so I know how hard it has been to get to the point where one can start writing actual software.
Now to my suggestion. I would encourage everyone that make Gadgeteer hardware to submit 3D models to www.3dcontentcentral.com. From Solidworks (the software I use at my new job) it´s as easy as pushing a button to publish a design, but you can also publish most solid model formats like Iges, Sat, Step etc...
Together with the new breed of low cost 3d printers, designing functional hardware is just a very small step away for just about anybody.
