Hrm, I can see where the confusion is. Actually, on the sidebar of each project, you can see that the projects are creative commons.
The "All right reserved" is for Cubehero itself, not the projects hosted on it. I actually took the lead from Github, as they also have "all rights reserved" at the bottom of their website as well, even though they don't lay claim to the projects hosted on their site (AFAIK).
It wouldn't make sense for me to own what you upload. I want to provide something useful to people, not to Own All The Things.
What would make it more clear when you're looking at the project? Bigger license badge?
Well, I looked and I didn't see anything at all about license. Do you only see the badge for already uploaded projects? Why would I look at existing projects for licensing terms?
It seems like anything like this should try to educate users about appropriate open-source licenses, and make license selection a highly-visible step in the upload process. It would be a shame if a community like this were plagued by the kinds of issues that eg. game mod communities suffer from due to unclear licensing status.
And they definitely need to make a clear statement about what rights the site gets and what rights the uploader retains.

Hi there, where would you like to read about this information? Perhaps a "About Licensing" page in the foot? Or simply bigger license badge on the sidebar of each project?
I think I'd like to see a Terms of Service link. GitHub's does a pretty good job of clearly explaining the situation.
Also, I don't think using or encouraging the use of a CC-Noncommercial license is a good idea, since it would prevent you or anyone else from offering 3d printing as a paid service to those who can't afford their own 3d printer.
