Nine Graduated Voronoi Clay Stamps

Ranging from 40 to 200 facets in 20-facet steps, these Voronoi clay stamps feature proportional strut sizes – from 6mm to 2.8mm (0.24 to 0.11 inches) thickness – for visual and structural balance. Each ball is about 60mm (2.4 inches) in diameter, a comfortable fit for most adult hands. But each can be scaled up or down for different applications. The struts will survive a 50% size reduction.

(The first version of this project, which I did not publish, used 3mm diameter struts which looked wimpy on the simpler clay stamps. So I redid them with dynamic sizing, which seems better.)

The wealth of patterns gives you great flexibility for designs, from fine to coarse textures. And you can resize them for more dramatic results.

Want some cat toys? Shrink them to catspaw size. Want even more cat toys? Here's my collection.

These print fine in PETG. I used PLA supports on my Prusa XL, limiting supports to the lower parts of the model with a support blocker.

(The Things You Learn: I imported five of the nine sizes to Prusa Slicer to print samples for this description but when I added a Support Blocker it would only affect one stamp at a time. After wrestling with the problem for a while I figured out how to block support for all five: Select them all, then right click and Merge them. Now the support block affects all.)
