I know that the B9 Creator needed to add a gasket behind the lens to keep out dust (after adding spacers). Is this something that you will provide, or will this need to be sourced/created individually?

Also, when you say 2-3% pigment do you mean 2-3% by weight? For example if I have 1 liter of SubG+ (unpigmented) how much red resin would I need to add?

Thanks!
