This is a fully 3D printed crossbow that I’ve been designing and testing for months, and I’m excited to finally share it on MakerWorld! It’s a rubber band powered mini crossbow that shoots surprisingly far for its size.

The more rubber bands you add, the more power it produces. (Tip: you’ll get the best performance by looping a single band multiple times rather than stacking on more bands.)

Assembly is required, and I’ve included a full video tutorial that shows the process step by step. Please make sure to use the provided print profiles—through extensive testing, I found that certain areas need extra strength to handle the stress, and these profiles ensure safe and reliable prints.

⚠️ Safety Note: This crossbow is powerful enough to cause damage. Do not aim at people, pets, or anything you don’t want broken. Treat it like a real tool and enjoy responsibly.

Sorry for the bad filming, let me know if you have any questions!
