NOTE - this utilizes a spring from a pen, the exact model really matters so feel free to remix this to work with any pen you like! although please add attribution, this is public domain but I want some attention.

Hi! new here,

this includes a small launcher and a small rocket designed to be used with a spring from a pen, nothing fancy or even that complicated. With the spring I used it only managed to go up to a few meters up but this is, like I said, very dependent on what spring you use.

I just made this and printed it in an hour when I was bored, and I wanted to share my creation to the world!

This takes inspiration from when I took the head of the pen and used it as a projectile and found out it can actually go pretty far. So natrually, the first thing I did was make a simple but better 3D version of it.
