Brush, Pen or Pencil Stand - Modular Voronoi

Simple Voronoi patterned holder for brushes, pens, or pencils.

I created this to fill in my empty space in https://www.thingiverse.com/thing:4060523 so the hexagon dimensions should fit in with those specs.

I've included the assembled model that I used for myself, but also separate cells (suffixed with: `_low`, `_mid`, `_high` files) and separate modules for the cells (suffixed with: `_level1`, `_level2`, `_level3`).

This model is very hard to print on FDM printers (and if you do it successfully, I would love to see the results!). I've done it on a Mars 3 resin printer.
