Paper Rocket and Paper Dragster Nose Cones
prusaprinters
These are meant to attach to paper rockets and paper dragsters. They are modeled for use with ½ inch PVC rollers (0.840 OD), but could easily be scaled for other sized rollers. On the rear of the nose cone is a small hole meant for a size W114 eye screw for testing in a vertical wind tunnel (I have not yet gotten this to work consistently). I use these with a box fan and a rudimentary wind tunnel made from a box fan and a pair of folding tables to measure the wind resistance of different nose cone geometries in middle school science classes. Note: To empirically compare the performance of nose cones, I recommend adjusting infill, wall thickness, and/or top and bottom layers so that each printed nose cone has a similar mass.
