X Axis Idler Mount With Tensioner Ver.2 (K8200 / 3DRAG)

This my second version of the X-axis idler-pulley-mounting, with a belt tensioner added. This device allows moving the idler in all directions you need. In addition, it is thereby also possible to use different pulley sizes.
It works fine together with my X-axis motor-mount which can be found here (http://www.thingiverse.com/thing:253741). This accessory is the preparation for the update of the Y-axis to GT2 belt transmission.
Info: There´re two versions of the outrigger.
