Customizable Scrub Brush

A customizable OSAT scrub brush for cleaning tough messes. Customize the size of the brush as you like. Change the size of the bristles to match your printer and print settings. One bristle dimension should be 0.001 mm less than the nozzle width and the other a multiple of the layer height. The spaced_bristle.scad has better printability and the OSAT_scrub_brush_#'s have been generated using it. OSAT_scrub_brush_1 is a small brush that is useful for dialing in bridging settings.
