I made it a little loose because it should be easily screwed in and removed by a child using the toy power drill that comes with the toy. My print in my pictures came out perfect (worked well without polishing) except for a little black abs plastic impurities that I didn't realize were still in the bowden tube which shows up as black streaks in the print.Fully usable. However I may do some further neatening of the design at a later time and update.
