Description
UPDATE Feb 2013: Well it doesn't print well with my 0.5mm nozzle. The wall where the hole is close to the side is too thin, see photos. I may try it scalled to a larger bolt size and play with slic3r settings a bit.
This is not a direct derivative of makerslide thingiverse.com/thing:8992 as it does not include the spacers.
This is based on the spec at buildlog.net/sm_laser/drawings/b18001_rev_3.pdf
I couldn't see why a metal one would be any better than a printed one. So I made one in SCAD.
I've also included a plain spacer to match.
It's also all zipped up for easy download.
The original STL of the Eccentric Spacer is at makerslide.com/
It and my version is for 0.281" 9/32" 7.1mm hole with a M5 bolt.
However you can modify easily for other sizes.

Instructions
Print
Shove in a 9/32" hole
Mount a bearing with a 5mm ID, using a M5 nut/bolt
Adjust the bearing to fit the rail mount using the hex section of the spacer.
Use the plain spacer to have idler wheels at the same height.

Great idea, but the compression forces on my CNC rail setup are probably going to deform it - thought about doing a plastic one, but never got around to it, so will give yours a shot!
