Lead_Screw_Bracket (Self-Adjusting)

I feel that a fixed Lead Screw Bracket, as in the D-Box, invites trouble.
It presupposes that the bed supports will be horizontal. They are never. Close, but not quite.
The lead screw nuts can take a little bit of an angle against the lead screws but not much, they are not meant to. And before you know it the torque results in more friction then the stepper wants to handle.

These self adjusting lead screw brackets can take that angle without bothering the lead screw nuts with it. There are 2 versions, 1 full plastic, called simple, and 1 with ball bearings.

Because, after I made the full plastic one, I began to wonder what the pressure between the 2 parts would do to the friction between them over time, plastic being plastic.
It worked completely according to plan and I think that after mounting very little, if any, adjusting is needed until such time that there is a change somewhere that would influence the position of the bed supports. And I am not sure whether at that time
