Alright I've decided to start making these things myself.... I've got a crude prototype setup that I need to test, if all goes well I will draw up some plans and post them here so that anyone will be able to have the part 3d printed. I wanted to be sure that Mark wasn't making them anymore before I start on this though. I'll update this thread with the info when I have the chance, if anyone happens to have one of these and can perhaps send me a simple drawing it'll help me cut down the time to get a final 3d printer ready file rolling.
Again, I have no intention of selling these as I have nothing but respect for Mark, and in honesty I would rather have paid him for this idea than go it on my own. And as long as no one gives me a good reason not to I will post the info for all of us to use as needed.
