Thats the 2nd half of my problem, I only have a 28 volt, 11 amp switcher in

FWIW, I have the mixed rubber washer/fender washer style dampers on my

Why limit your design to a tool holder? Make it a 3/4 shaft so any tool
holder can hold it. Of course if it was a popular design you would think

As Andy already mentioned, 3D printers are optimized for speed and
