About this 3D model

This is an updated version of the carriage designed by kolergy for his enlarged rostock. The first upgrade is that it no longer uses zip-ties to tensions itself around the linear bearings, but it now uses bolts that tighten the bearing sleeve. The other upgrade is that it no longer uses the 3D printed joints (as they are not solid enough and have too much play in their movement for my liking) but rather, it uses Traxxas long and short rod and ball ends which eliminate a lot of unwanted movement: http://www.amainhobbies.com/product_info.php/cPath/1_25_1466_74/products_id/2815/n/Traxxas-Long-and-Short-Rod-and-Ball-Ends A hot-end platform will be uploaded soon with customisations to match this.
