I probably won't be adding any new split heads for a while (I do have them for some of the sets). It makes the heads easier to print on smaller printers, which makes them more accessible for people who are new to printing (in most ways, that is GOOD) and I don't have time to teach a bunch of people how to use their printer or glue a head together- so I don't think I'll be adding any new split up bases until I have time to also make tutorials
