So other than the default butterfly CAD file that comes with the printer, I tried to print a BB-8 from Star Wars. So I downloaded these files from a Star Wars fan club that did R2D2 and now BB-8 builds. So this is the BB-8 head piece. I must say for a 300 dolllar printer, I think the quality is alright. Granted this print job took something like 14-18 hours of non stop printing. Now that I got the issue resolved maybe I will print the rest of it. Hopefully someday down the road the technology improves and it doesnt take as long.
