Earth-friendly Rocket Pen!

After designing the body of the pen, I then cut it in half to integrate a threaded twist/push mechanism to hold pen refills (Parker ballpoint, Pilot G2, etc.). It does need a spring to allow it to retract the pen tip, so I used the spring from a freebie twist/push pen, but any should work. If you want it to fit without any threads showing (like in the photos), either use a longer refill or add some broken bits of support material from another print. Maybe the rocket pen can remind us to take small steps (like using it instead of disposable pens) that can help us avoid needing to “rocket” away from Earth one day!
