This is a remix of nilocwng`s excellent Z-axis brace for Zonestar P802QA. I have increased the thickness of the base plate a little, extended the forward webs and threw in a few rads.
This and the upper Z axis brace make a very big difference to the rigidity of the assembly and reduces wobble on the Z axis.
Would recommend using it with the remixed upper brace here:
