Summary

Very strong shelf holder, I loaded it 20kg.
It is easy to put on 6-8mm dowels.
The depth of the shelf is 15-20cm.

Update 06.10.2020 Remodeling in Blender 2.90. Much less lag in comparison with the old version.Gyroid mesh is now not triangular, but quadrangular low poly. Which gives much better anti-aliasing with the subdivision modifier. I haven't printed this version yet, but everything looks pretty good in the slicer.
