I was able to 3D print the nut retainers today and they came out great, still need to order the Shapeways parts to really put the entire assembly together. I'll be kicking that order off this Friday and will have enough components to get the Z-axis together and operational. I'll keep plugging away at the design for the X and Y axis but wont be able to get parts in for those until after this second round of judging.
I also took a moment to update the GrabCad project located here: https://grabcad.com/library/tome-3d-printer-1 with more finished components. Please note that these parts may change over the course of the design, and new versions will be marked V2 when I update the files.
