CAD Design for Honeycomb Carbon Fiber Tub and Body for 911 Coupe . Here files Incudes STEP for all assembly and Stl of surfaces for 3D printing for negative mold for making carbon fiber surfaces of car's main body. It is design a low total-cost composite tub, roll cage and body system for a 911-style coupe using low-cost carbon/honeycomb sandwich sheets as the primary tub structure. Most structural parts should be flat / single-curvature sandwich panels that are CNC cut, then assembled with a “glue + screw” method. Its mostly just converting the scan to NURBs and consolidating the attachments to the carbon tub.
