East3D gecko Z bearing rod brace

This is a great working Z rod bearing brace for the East gecko coreXY
uses m5 screw and t-nut to attach to the 2020 extrusion
and (optional)uses a m3 screw to lock the 608-zz bearing in place .
i didn't lock the bearing in place with the m3 screw. it dont need it realy.
