GO Bowl Plans

Hello fellow woodworkers and go players!

I'm looking to possibly turn my own bowls as my old set were , umm... Not Expensive To begin with, and While im' not QUITE ready to bandsaw one of mine in half, I'm just looking for dimentions and a drawing of a cross section of a typical bowl. Im also a big fan of 3d printing, and have some wood filled filament that I'd LOVE to print a set of bowls and lids out of, but that stuff was Not Cheap, so thinking i'm gonna model a 3d bowl and print a few to make sure i get the size for my stones where i want (think i use 28s)

Any leads and drawings would be a wonderfull help!

p.s. Im ALSO doing the same for GOBAN Legs, i'll come back and edit when i get that post up!

THANKS!
