TLDR: Teammate 3d printed a handle for me, it is sweet.
I have always used a wooden extension in my stick, for the last couple years as I have become a better skater I have been slowly cutting the extension down. The sweet spot for me seems to be only about a 1/2in extra onto the stick so I build up a knob using half width tape.
Cutting down a full 6inch wood extension seems like a waste and adding some extra weight - asked a teammate with a 3d printer "hey can you make this"
It came out awesome - I just need to lightly sand down the edges to save the palms of my glove and then toss 1 wrap of tape around it.
