I haven't actually done this yet for any parts on the Montero, but I've been thinking about starting a Montero part library on OnShape for general community use. If you're not familiar with OnShape it's a cloud based Solid modeling program, free to use if all of your parts are public. Private access costs a nominal membership fee
The neat thing is that if there was a public repository of these parts anyone could use a prototyping shop (protolabs or similar) or a 3D print shop (stratasys direct or similar) to print/machine their parts on demand. Prints could be generated as well for local shops. And because it's web based we could get people from all over the world to contribute (maybe.)
If there is interest my first thought was to draw up a gen III strut spacer or similar easy part to gauge interest.
