These are some of the tactile textures as described and used in "A Quantitative Perceptual Model for Tactile Roughness." This set currently includes the bump textures, numbers 1-13.
Textures are 25x25mm flat plates with raised bumps shaped as truncated cones 1mm tall, with semi-sphere caps 0.3mm in diameter. Bumps are arranged isotropically with a prescribed average spacing from 10/16 mm to 26/16 mm. Spacings are etched on the bottom of each texture.
Textures may or may not require supports to avoid falling off of the platform, depending on the adhesion of the resin and build platform. Our small support structure is given as an example.
