For anyone that fills their own DI containers, check out this genius 3d printed set of tools. Top fits perfectly in the base, the funnel threads on to stay in place (and keeps resin from getting in threads), and it comes with a tool to tamp down the resin. The idea was from a r2r acquaintance; I am making sure with him before I post his info but hmu if you’re interested and I’ll get you in contact. This is such a clever idea that solves so many problems.
