Simple part to print, to replace the thumb stick rubber on XBOX controllers.  

Print in TPE or TPU, stretch over.  

I printed with Fuzzy Skin at 0.3x0.3mm – this is my personal taste.  

I did use supports on build platform only, and printed it with the bottom to the platform.
I also used variable layer height, with very thin layers for the top section, so that the fuzzy skin was everywhere.  

I also printed with enough walls to make it 100% infill effectively, and used some heat to make it flexible enough to stretch over.   This is definitely personal taste again, but I wanted it to be solid like the original, and not squishy.
