Better lithophane stabilization towers

To prevent wobbling when printing large lithophanes.

Improved steadier version from my previous upload with better print bed adhesion areas.

Approximately 160 mm supports to be put on each side of large lithophanes.
90 degree supports in case of large prints put diagonally on the heat bed.

Import the .stl file twice in the slicer and use x-ray view to rotate and move them on each side of the lithophane. Then insert 1-2 mm into the sides. The supports can then be easily snapped off.

Scale them up or down in the slicer if needed or use Pause at height to stop the printing above the lithophane.

Note I have cut the corners on the flat stl compared to the images and video.
