I would say that the fit on the blaster is perfect. Not tighter or looser. I have printed mine with 3 layers on the wall for a total wall thickness of 1.2 mm with 20% infill. The adapter feels very sturdy and I do not fear that it will break from repeated removals and installs. I would not change a thing! I plan on assembling it tomorrow once I get all of the parts done. I will keep you posted on the results.
