Prusa MINI Z-Axis Support Brace Remix

I modified @victor's brace and added a mount for the top of the 3030 extrusion to give it a little more stiffness. v2 v3

UPDATE:  I added a new “narrower” Z mount width.  I had at least one person say it was hitting the extruder.  Mine was really close but not hitting.  I reduced the overall width of Z mount by 1 mm.

 

The picture of the brace on the Mini was my version 1 and I then added more support on v2 the top and also put a chamfer on the leading edge to miss the Y axis bearing holder.  Then I thought more simple and made it look like Victors but just with a top connector.

I am in the process of printing v3 and will upload image when done.

You DO need to print with supports but they snap off easily.
