Hey all,
Honestly, all I can tell you is what I know myself. Russ has been completely off grid since February and hasn't responded to any e-mails or messages. As Schlitzie mentioned, he still hasn't been on the RPF since late January. I don't know if he's tied up with work, if something happened to him, or if he's even still active in the industry. (If anyone has had any contact with him about unrelated things, it would at least be helpful to know if he's returning anybody's messages at all.)
With that said, I spoke with Joatrash and he's going to try to offer a 3D printed plastic version for those who want an alternative option. If that interests you, I would suggest you check it out.
