I had to do something about the stiffnes of the bracket, as it's now it gave some xtra backlash. Latest development of the bracket is the version 4.1. The latest version is much stronger and I hope it work even better.
The last changes, page 8:

It needs some practice to work with 3Dprinted plastic, later all this supports to get it strong enough will be there from the start.
