Printable hole test array
An array of holes, from 1 to 30 mm in diameter as printed, designed to test the ability of a 3D printer to handle voids accurately. You can of course scale it as needed to test a larger or smaller range of sizes (for example you could try scaling by 0.1 to get holes between 0.1 and 3 mm to see where a system fails and how). A complement to the grid test print device I posted, which tests ability to print thin walls.
I am uploading both the STL file, and the Art of Illusion script I wrote to make arrays of holes of various sizes. Photos of actual printed results will be uploaded when I have time.
