Ok
@DarthRaiderBob, I printed up a few test parts to test fitment etc etc... was getting some pretty heavy ringing and found that i have a lot of slop in the z screw. I ordered some new parts ( and a dual screw kit ) to hopefully tighten that up. I have the two halves modeled up so that they can snap together, but that heavy ringing was causing some tolerance and clearance issues that I couldn't ignore. Anyways, some colorful language and a small fit of rage later... new parts are coming! But, they won't be here until Wednesday.
