We can do a group buy. If we can get enough interest for 15 sets Radium can make up the difference in cost to get 3 different sizes. Any less than that and we are diverting funds mostly towards developing our wheels at the moment.

Standard (2-3 week) shipping to USA is 20.5AUD / 14USD
Can do custom thickness on request, although I suggest doing a group buy of 3 or more to keep cost down since the rubber is 1sqm minimum order and like $35 cost just to cut the sheet off the roll.
I know 12mm should be good for double stack 18650 with no BMS ontop, and for double 2170 with BMS in electronics compartment you need about 25mm… which has been done but you need through bolts to get things to line up. Could get away with 20mm if battery was built slim with all wires running down the sides.
