Yeah, as Chris said (because he too has asked me about printers), we do want to make more specific printer names just so people can filter their search in advanced search to see prints made with their printer. That way the prints info is more valuable to them. But, it is limiting when users can't find their printers.
However, we do want to include as many printers as we can. As you mentioned, it is hard to keep track of all the variants out there, but whenever we receive a request for a new printer to be listed, we almost always add it to the list.
Thanks @Chris_Halliday for making a list of RepRaps that are current, and not on the platform yet! I've added a list of 56 RepRap printers to the database, so hopefully that helps users find their model if they have a RapRap. That being said, if anyone else has a printer (RepRap or not) that they'd like to add on the list, just let us know!
