Bolt Action Pen

I saw a few pens on Ebay & YouTube that had a bolt action mechanism that I really liked so I designed these two pens. Just add a 5mm compression spring, M3 screw for the bolt handle and a 3-5mm ball point pen insert (refill). https://www.youtube.com/watch?v=aJV04GyW41Q https://www.youtube.com/watch?v=7UUlbczdqAU https://www.youtube.com/watch?v=18w-8JvSHI0 Note: I will be posting pictures as soon as I finish printing it !Don't forget to CHECK OUT my other designs and FOLLOW my DAILY KooKoo uploads, Enjoy ;)
