Spacer for SW06UU Linear Bearings
by dnewman, published
Also these spacers can be used on the Y-axis carriage as well as the Z-axis. As with the Z-axis, you would be replacing the press-fit adjustable bushings with these linear bearings.

Indeed, my ToM sports that same X-carriage. And, like MakeALot, I put a pair of those linear bearings on my Y-carriage and held them in place with a spot of glue after letting them settle in. (Third to last photo for Thing 9420.) However, I figured that that spot of glue would give way eventually so when Jetty mentioned these Z-spacers to me, I jumped on them.
Cool, I've upgraded my X-Carriage with these bearing using this thing: http://www.thingiverse.com/thi... so It's time for the Z and possibly Y now. These bearing are also known as LMB6UU

To adjust the spacer, you will likely want to change the two parameters EXTRA and t in the OpenSCAD source file. EXTRA sets how large to make the inside hole in the spacer relative to the outside dimension of the bearing. It is a multiplicative factor set to 1.04. Make larger or smaller so as to get a good fit with minimal play. The parameter t is the thickness of your panels. Again, adjust so as to get a good fit.
1. Print out four spacers for the Z-axis carriage and two more for the Y-axis carriage if you will be adding linear bearings to it as well. Use the "multiply" section of skeinforge with 3 columns and 2 rows in order to get 6. However, you may first want to print just one as you adjust the fit.
2. Slide a spacer onto each bearing. Secure one end with a 9/16" clip.
3. Install the bearing and clip on the other end with another 9/16" clip.
