Designed for the Railcore II printers, the Idler Mounts for Magnum Pulleys remove the overhang on the left side of the printer and move the Idlers INSIDE the volume of the printer. It shortens the belt significantly by 6-8 inches. One of the benefits of this is that it's going to be even easier to enclose the top of the printer, which is available from Mandala Rose Works at http://www.mandalaroseworks.com/product/topEnclosure.
PLEASE NOTE: You will need to use an 8mm bolt instead of a 10mm bolt for attaching these mounts to the aluminum extrusion due to the countersunk holes.
