Cool design! The hexagons provide great grip. I have been experimenting with settings to see how it affects the tone,feel,and appearance. Specifically I tried to see how transparent I could get it with the clear. I got pretty good transparency by making the pick 1mm instead of 1.3,and printing hot with 0.08mm layers. Also by printing on a smooth pei sheet and with ironing in Cura. Each print sounds a little different on the attack. More experimenting needed.
