The file 'Stackable Painting Prism 3D Printer Model' is (stl) file type, size is 8.7KB.
This is a long version of my Stackable Painting Pyramid ( https://www.thingiverse.com/thing:2781260 ) This is great for painting boards or trim. The top is 100mm wide. It has notches on top to allow extra paint to flow away better. These are stackable with my original ones. This also makes a good bridging test.
