Enlarged Rostock Carriage V1.0 for 12mm smooth rod & KB-12-WW bearings

An earlier version of this design can be found at http://www.thingiverse.com/thing:79147. Due to time constraints, I opted for minimal changes to the carriage. Once the printer is operational, I will evaluate and refine the branch attachment to minimize movement caused by bearing play. Key improvements include aligning linkages with center planes of bearings both vertically and horizontally, aligning belt mounts between bearings, and using M3 screw-based bearing housings.
