Grappling Hook Pen

thingiverse

This is the Grapple Hook Nerf Bullet by Redstone W@rrior on Tinkercad as a Pen. Tie a string to the hook on the pen shaft and attach the other end to the hook. This will give you a small grappling hook that you can use effectively. I would strongly advise against attempting to scale a building with it, however.
