Yarn seems fine, but the hole in the spool is too small to fit the Prusa Mk3S spool holder. You can get it working by removing one of the levers from the spool holder, putting the spool on it and reassembling it. Edit: After reading another review I found that you can remove the center of the spool to make the hole bigger. .
