Falcon 9 pen (bic)

thingiverse

This Falcon 9 pen utilizes a low-cost Bic Cristal pen that can be easily detached. The fairing/cap is secured by pressure fit, but if it's not snug enough or too tight, you can apply a small piece of transparent tape around it or sand it down for a secure fit. I've created two versions: one with the engines attached and one with the engines separate to allow for more detailed printing. The second version is similar, but thicker (1.2mm instead of 0.8mm). This revised design was inspired by freebeeromg, but I designed it from scratch. I may also attempt to refine the end to make it smoother. (PS: Please disregard my limited coloring skills; permanent marker tends to bleed along print lines.)
