Stackable painters pyramid

thingiverse

I required some soft-point pyramids for my project, and I had found ones posted by CherryTreeCNC that caught my attention. However, after printing one, I realized they had two significant drawbacks for my needs: 1) they wouldn't stack properly for storage and 2) they were excessively substantial even for the doors I intended to place on them. To address these issues, I modified the lower sections of the design by thinning them out while maintaining the nice sphere at the top. This change allowed me to achieve a more suitable balance between stability and weight reduction. During load testing, I stood on one pyramid until it felt like it was about to collapse under my sneaker's weight, which I estimated to be around 50 pounds. While this approach might seem unorthodox, it provided valuable insight into the pyramid's structural integrity. When printing multiple pyramids at once, I encountered an issue where some of them would pop free from the print bed; I attributed this problem to the thin base section. To resolve this issue in version 2, I added a thickened bottom edge for improved adhesion and stability during printing. For those who want to replicate or modify my design, I have made available SketchUp files and STL files for download. Additionally, I posted a Cure 3MF file that includes eight pyramids arranged in a tight grid for convenient reference.
