Hi there, I'm trying to build a 3d printer for an aqueous environment - and I need parts that are all stainless steel or aluminum. However OpenBuilds (and no other site for that matter) doesn't carry a M5 tee nut that fits the OpenBuilds aluminum extrusions! Anyone have any ideas? I tried printing some tee nuts but they strip the threads out too quickly, and now I'm forced to make my own tee nuts out of aluminum which is just a pain. Thanks!
