Great model, word to the wise don’t print the pull bar with a brim unless you want to spend 2 hours getting it running smoothly

his print absolutely exceeded my expectations! The design is incredibly clever, and everything fits together perfectly, feeling solid and sturdy right out of the printer. The zip cord pulls smoothly, and the rotor launches with impressive speed and power — it’s surprisingly thrilling for such a simple mechanical design. The propellers spin cleanly without wobbling, and the launcher handle is comfortable to hold and operate, making repeated launches fun and effortless. I love how easy it is to print and assemble — no extra hardware needed. The tolerances are spot on, so even after multiple uses, there’s no cracking, loosening, or wear. It’s a satisfying mix of smart design and reliable performance. Watching it work is addictive: the kinetic energy transfers so efficiently that every launch feels powerful, precise, and exciting. This is one of the most entertaining prints I’ve made. Quick to build, easy to use, and endlessly fun to show off, it demonstrates how simple designs can be incredibly effective when executed with care. If you want a fast, smooth, and surprisingly powerful zip launcher, this one is absolutely worth printing — you’ll be impressed from the very first launch!

Very fun little copter. You should make the rotor blades thicker because a friend stepped on it and it broke. Still flies well though and it got taken away twice at school. ;)
