A remix of a remix :D
I used max infil and 0.2mm layer height with PETG to really make sure that the Z-brace is doing it's thing and keeping the Z-axis in one place.
The author remixed this model.
Used original model from “Brolin Workshop”, filled all empty hexagons.
Took "TWB" idea of adding an angle support, copied it three times in different sizes making sure that applied force from axis bending is equalised.
