Description
This is a modified version of Jonas Kuehling's "Y Carriage Mounting Frame for Slim LM8UU Holders". It includes two mounting tools: snap_on.stl and rod_end.stl.
The idea is to have a maximum distance of the smooth rods by printing two connected LM8UU holders diagonal on the print bed. You can make a larger print bed for your next new 3D printer with this diagonal technique.
This technique causes a poor alignment of the two holder pairs. But the additional mounting tools will help there.
If the smooth rods are not parallel, a rod fixation clamp can break apart after a while and bearings may fail sooner.

Instructions
Adjust the OpenSCAD file and change the frame_length and rod_dist values.
To use the OpenSCAD file you need the extra "lm8uu-holder-slim_v1-1.scad" from the ancestor version.
Keep in mind the maximum of your print bed diagonal size. The STL-files are for a rod distance of 138 mm from center points. (There is no specific reason for 138 mm.)
You can print the connecting snap_on part, if you need more help for the alignment of the holders. The rod_end part is for checking that the rods are parallel.
To get a more precise alignment, mount all bearings and the smooth rods before the fixation on the bottom plate.
Update:
- added a M3 thumb cap
- added a T5 belt tensioner
