I'm sorry it is giving you issues! You may want to check the comment thread here between myself and CharmPeddler as it has some troubleshooting steps for when you're running into things being too tight on this. The threads on the base are undersized by 0.325mm from the top, so if they are super super tight, you most likely have an over extrusion issue going on. Were you printing in PLA?
