3D Printer 4xLM8UU Minimal X Carriage (with symmetric/balanced tensioning mechanism) for F694zz bearings & more [#SCOUTcorexy design]

thingiverse

This is a major upgrade to the original 3xLM8UU Minimal X-Carriage with balanced belt-tensioner (http://www.thingiverse.com/thing:1505842) I designed for my SCOUTcorexy 3D Printed printer (http://www.thingiverse.com/thing:1487375). It's not meant to replace the existing design, which works flawlessly, but rather offers an alternative with four bearings for those who prefer it. To make this new X-Carriage more versatile, I've made it modular, allowing users to easily swap out belt-grippers as needed without reprinting the entire assembly. For added convenience, I've included a nut in the X-carriage body that holds the module in place, preventing any potential movement issues. The increased rigidity provided by internal belt grippers remains intact. If you have questions, please don't hesitate to ask - I'll do my best to address every inquiry.

Update: On August 7, 2016, I added a Y-carriage that complements this X-Carriage design, with rods spaced 40mm apart.
