LEGO ring w/studs (less bridging)

thingiverse

This is a remix of ZhilDV's Lego ring. I couldn't get it to print well because I don't have proper cooling for such a large bridge and supports would be a pain to cut out post print. I just found someone else's 2x2 and merged it with the inside. On my printer, I had to print at 1.05% so that the lego piece would fit the corners. I only did the 15mm size because that's what fits my kid's fingers. I have the tinkercad saved as unmerged objects so I could rework another size on request. It really was simple to do, though. Instructions I printed mine 1.05% because the lego hard corners were too perfect for my printer's sloppy rounded ones. If everything prints nicely, you should have a firm base to hot-glue a 2x2 flat to.
