About this 3D model

This is a test object to determine real-world 3D printer resolution and behaviour when confronted with sub-resolution features. Units are millimeters. It consists of an array of otherwise uniform grids of decreasing wall thickness (2, 1, 0.75, 0.5, 0.4, 0.3, 0.25, 0.2, 0.15, 0.1, 0.05 and 0.01 mm). I have also included the Art of Illusion script I wrote to generate the grids, in case you want to vary the grid size, wall thickness, periodicity etc.
