Stackable painters pyramid

I needed some soft-point pyramids. I liked the ones posted by CherryTreeCNC but after printing one, realized they had two flaws for my application: 1) they don't stack for storage and 2) they were *way* more substantial than needed even for the doors I might lay on them.

So I thinned out the lower sections but left the nice sphere on top.

Load testing - I stood on one until it felt like it was going to punch thru my sneaker, so I'd guess that was 50 lbs. yes, this was a highly technical approach, but whatcha gonna do ?

Withthe thin base section, printing more than 4 at a time seems to cause some to pop free whhile printing; v2 will have a thickened bottom edge for better adhesion.

sketchup files and stl are both posted for download. Also posted the Cure 3MF file with 8 in a tight grid.
