This is my bracket design with adjustable bearing supports to help align the leadscrew and also to remove the load of the Z coupling improving the Z movement.
The bottom bearing support uses one thrust bearing (10x18x5.5) and a printed collar. These will hold the weight and remove the load from the coupling.
There are 2 lower brackets. One with base and other without base. I had to design both because most people use the brackets from Robcad with base. I use modified Robcad's brackets with no base so that the entire printer structure is flat on a wooden base.
The top bracket is untested. It also has an adjustable (radial) bearing support to help align the leadscrew. If the lower bracket is used, then the collar for the upper bracket is not needed.
These designs are based on the work created by Jim Marks (http://www.thingiverse.com/thing:1676571).
Before printing, rotate the parts in your slicer so that they lay correctly.
These designs are under test so any suggestion or modification are welcome.
