Needed to replace a couple parts on my Hario Skerton Pro grinder and decided to try and upgrade its stability and grind consistency.  

Printed on Bambu Lab X1 Carbon

Bambu Labs PAHT-CF

0.12 layer height

3 walls

Printed each piece at 94%, 97%, 100%, 103%, and 106% scale for fit to try and account for shrinkage and dimensional instability of my filament.

For the Burr Adapter I used 106% scale and for the Shaft Adapter 103% scale.

I still had to do some sanding to get a nice tight fit.

Would recommend doing a similar scaling with whatever filament you use to account for shrinkage and to find the best fitting size.   I included the .step files if you want to modify the source design.
