Just a quick print in a pinch for those of us who didnt get a drain adapter (or lost it) and cant wait for online stores to ship. Print in whatever youd like. I used ASA to keep it around a while. Press a little the first time you thread it and should go on easy after. NPT hole is to size but not threaded. I buried the fitting to the nut and it did not leak.
