V2 of this exists at http://www.thingiverse.com/thing:699285. The X-Idler at the 624zz location broke on me, so I made my own parts to use what I already had. If you look at my picture, it's a beta version; this is the updated version with some minor issues fixed. I will print this as soon as possible now that I have a functional X-Idler because when that broke, mine fell apart. This design adds 5mm more to each side than the original so you can reinforce them if needed and still make it easier for beginners. Instructions Use an M4 screw and nut for mounting. To tighten, insert an M3x25mm bolt with a 3mm flat washer on top of the idler. This was designed for a layer height of .2 mm and 45% infill.
