Better Idler 2040

This uses http://www.thingiverse.com/thing:651469, or another 20mm round spinning thing with a 5mm bore. This was designed for my Tevo Tarantula, but can probably be used on most any 2040 extrusion as a idler. The design uses a m5 nut, 25mm m5, 2 m4x10 and t nuts, for the printed pulley you need two 626 bearings and 2 1mm spacers. The design has tight tolerances, but I was able to fit everything together easy enough. You can set the m5 with the 25mm if you need to.

Please post your makes, or pic of the rig with the parts if you use it. Thanks!
