Made cutouts to reduce material & help users pinpoint knee joints.\nArbitrary dimensions for cutouts & sighting guides.\n\n \n \n Assembly & Materials\n4 mm bolt\n4 mm locknut/nut\n4 mm washer if needed\nCenter hole is sized for 4 mm bolt.\nPrint the same thing twice; a 0th indent is provided & should be visible for most angles. Line up with periphery of one in front.\nAdd numbers in sharpie yourself. Shaded regions are 35 to 25 deg on Lemond goniometer.\nNote that if you scale print, which you probably will, the hole in middle won't fit a 4 mm bolt.\nFuture\nadd graduations for measuring handlebars like BikeFit Goniometer\nmove graduations around as users suggest\nredesign & optimize for smaller print beds (6" x 6")\nadd numbers\nforefoot measuring device
