From: Jay West: Friday, January 30, 2015 7:14 PM Here are some of my efforts, one of which is based on his: http://www.so-much-stuff.com/pdp8/cad/3d.php I've had excellent results ordering from Shapeways. The switch handles are not cosmetically pleasing when printed with the usual hobby gear, and the improved resolution of Shapeways' sintered nylon printer really helps. You'll want to seal the result -- the sintered nylon parts are very porous and magnets for dirt. Urethane based floor shines are great for this. The surfactants make it easy to just dip the parts for a smooth thin coat. (Twice works for me.) I also have (offline) minor tweaks to adjust the rest angle to more perfectly match existing switch handles, which I still need to have printed and test. (The ones there now are fine if you're ordering a whole set.) (The pictures there are just renders. Someday I should add photos of the actual objects.) Vince
