This design started off as an attempt to make a 2D isometric representation of a cube in the crown of a triangle. That's the C4 tier. The rest of it was basically just me trying to add more bars to the crown, as I am wont to do. This design should be easy and fast to cut, and I think it's technically an OMNI. Works in materials from petalite to YAG (RI = 1.50 - 1.83) with no changes.
