SCV8UU linear bearing block is the ideal replacement for printed or laser cut MendelMax Y-Carriage.
Simplified design by dumping the 2 stage print platform. The single piece of print platform is now seated directly on top of the SCV8UU's flat surface. It will slide above the aluminium extrusion with 1mm clearance.
The Y-Axis belt is clamped onto one of the SCV8UU to transfer linear movement to the print platform.

Using SCV8UU with Jmil's Compact Y Rod Holders (Thing:24510) is perfect because the print platform will be positioned slightly above the front aluminium extrusion with 1mm clearance. This allow the print platform to slide above the extrusion and not limiting the Y-Axis travel distance.
