Thingiverse is so slow now that it's almost unusable. They say they're working on the speed issues but....... It took me two days to upload a few pictures and the .stl files for a universal Li-Po charger stand that I designed. I almost gave up trying to post thanks for a file I downloaded a while back and finally printed today. I've found just a few other file sites but I'll bet I've barely scratched the surface of what's out there. Would love to hear what other sites you guys frequent. I love Thingiverse but until they fix the speed issue it's just too frustrating.
