Prusa i3 X-Carriage for GT2 belt

thingiverse

I'm looking for an X-Carriage that meets my specific needs, and I've found several good options with excellent features. However, none of them have all the features I want in one carriage. I need a hassle-free belt holder that's small and compact, like the one on this carriage: http://www.thingiverse.com/thing:840907. A big flat face is also essential for accommodating various print head configurations - single, dual, direct, and bowden. To support these configurations, I require mounting holes that can accept fittings from 22mm to 30 mm in size. The carriage's bearing holder design must be sturdy yet compact, capable of holding four LM8UU bearings to handle heavy payloads. Lastly, I want a cable carrier support for my wiring, allowing me to install a semi-permanent cable set on the printer that can be terminated at the carriage for plug-and-play print head replacement. To meet these requirements, I've designed my own X-Carriage. Next, I need to integrate an adjustable home sensor trigger for an Opto sensor, as I've already designed a new X Motor End with an integrated mount for this sensor: http://www.thingiverse.com/thing:922783. This integration will be possible once both the new carriage and motor end are printed and installed on the printer, allowing me to assess what's needed. Feel free to comment if you have any suggestions for further enhancements! Update 2015-07-15: I've added a version of the carrier without the cable chain holder. Update 2015-07-17: Source files now available.
