A Custom made FlSun Cube Carriage designed and created by me, Jason Routenberg, using size specifications from the original design made to fit the 3D Printer perfectly. This is for Dual Nozzle Cyclops or Chimera. I had made the Radial Fan duct separate, but with a support to make easier attachment. The BlTouch support is exactly 3mm for the smart configuration, so no need for spacing, just be sure the spacing if using Chimera style that the nozzle are correctly at the same level. All holes are made to fit 3mm Screws when attaching, except the carraige support holes. Those are the exact manufacturer specs.
