Description
Place your Z motors downside in order to lower the center of the mass of your frame so that deflection of frame caused by rapid printer moves during print is decreased.
Also the wires can be managed more easily if the motors are on the downside :)

Instructions
1. Print the file two times.
2. Print the Z axis joint. I printed this one: thingiverse.com/thing:32958
3. Disassemble Z motors and rise the X axis. You can use 2 CD/DVD cases and place them vertically on the print bed to support the X axis
4. Remove two perpendicular joints which connect on each side vertical 8mm smooth rod with the long horizontal M8 rod. Next you need to move this M8 rod through Y direction so that its axis is in one plane with 8mm smooth rod and as a matter of fact also with M8 lead screw for Z axis.
5. Mount the parts.
6. Lower your X axis and connect kardan joints. There may be some imperfections and axial run-outs of the lead screw. Try correcting the long M8 rod position
Good luck!

It could use a nut pocket for the smooth rod clamp.
(And if you are feeling ambitious, a right and left version so the smooth rod clamps face the same way. Yes I can get picky on some stuff:) ) but I've printed out a pair for a new build.

Are your steppers secured into the mounts some how, or is it a snug or press fit?

im having problems slicing this with slic3r. What slicer have you used?
I'm using 0.9.1 version, but I think newer version is available on github. if you are still having problems, try netfabb free software to fix the meshes. it's very useful with other projects as well :)
