Easier to Print Simonious' Supa-Flat X-Carriage
by Ember, published
This is a derivitive of Simonious' Supa Flat x-carriage that I have modified it for printability. His original x-carriage has nut traps that transitioned to holes, but he did not allow your slicer to generate any kind of bridging to print the hole on top of the larger nut trap, resulting in additional clean-up.
Pick the STL that matches your layer height and print. Use Simonious' belt clamps and http://www.thingiverse.com/thing:15218 for the bushing holders.
