I want one
Buying the drop down to the MT4 will save having to buy the M12
Please please do one GRID RC

Now that there are the 3D printers could you do a test run with them, its not as hard as alu but does it need to be that robust?

OR
How about releasing the images/work for it??? THat way people that maybe have a milling machine at home or at work that they can borrow and or 3D printer can do their own.

I know you guys put a lot of work into the drawings and cad stuff, maybe people could buy it from you?
