Happy i3v X-Carriage

Update 1/18/2016 This PETG carriage has performed flawlessly after a week of rigorous testing and a single 14-hour Delta Vertex print session, during which it took over five hours to complete. I've attached a photo showcasing the installed carriage. I revised the X-carriage design over summer with an innovative smile-engraved back plate; however, it showed promise as the "Happy X-Carriage," but functional tests proved inconclusive, leaving this design more suitable. Using Openscad for creation, Draftsight generated the 2D geometry, and TurboCAD's railsweep command helped form the ledge around the edges using a similar design process previously undertaken. Although sidetracked by other projects, numerous versions were tested; therefore, I have released this revised version to potentially facilitate another's endeavors. Strategically placing added holes with triangular cutouts enhances heat dissipation while diminishing vibrations, which could allow for smoother PETG printing in conjunction with 1/8-inch brass bar support to prevent rigidity loss during prints. If you plan to create one of these parts, three main configurations can be selected: Add 'ears' to ensure a strong connection between the print and the bed Include a cutout for a more substantial attachment using ABS as your primary material This modified carriage incorporates additional features to make it compatible with PETG: Dimensions for this assembly were extracted from Clough42's design: http://www.thingiverse.com/thing:335632
