If u get stuck Al i'll make u one! Black nylon, Alum, or Brass? Simple design tho, 8 finger nail notches around the rim. Just gimme the nod. (free trial offer)lol
I've been considering making a batch on a laser cutter thats available to me, delrin aint that expensive, can churn them out for a couple of quid a piece.
If theres a big interest, I'm sure i could make a bunch... i had a funky design somewhere...
