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
