3-1 Speed mutiplier for remote direct drive

So I redesigned this because it works well, and the bearing holes weren't the correct size and I wanted a way to tighten down on the tubing securely. Add some supports under the clamping part to make it more stable. https://youtu.be/MwEhKZO7G10 I printed mine with super dry Taulman Bridge Nylon, 3 walls, 4 bottom layers, 5 top layers onto watered-down 3D Eez on a build plate at 90C, print temperature 288C. Reference the original design for the Bill of Materials. I also added some precision shims (OpenBuilds) but washers should work well too - the point is to tighten down on the bearings so they're stable. The bolt used is a 5mm x 15mm with a lock nut. Also included are CAD files for folks out there to use.
