Customisable Nose Cone for Mini-Rocket

I borrowed the scad file made by lpaelke (http://www.thingiverse.com/thing:26370/#files) because I wanted to familiarize myself with the Thingiverse's customizer . I then changed the file so that everyone (those who do not know any of OpenSCAD) can use this file in the excellent Customizer Thingiverse. Enjoy...
