Pull-O-Copter

thingiverse

Based on the Toothed rack and gear module 1.5 by denmx, I created the Pull-O-Copter - a toy that launches a 100mm (or experimental 150mm) diameter rotor skyward with one swift pull! Perfect for kids and anyone who loves fun. It can be used outdoors or indoors without any hassle. If you experience issues with the files, try using the _fix files provided by HAMMER_T (https://www.thingiverse.com/HAMMER_T) to achieve better results. Thanks to HAMMER_T for providing the fixed files! The Pull-O-Copter in action is captured in a tiny video: https://youtu.be/WDU0ompqszc You'll need 2 m3 screws, with lengths of 10-13mm, to assemble this toy. Update 1: The rotor now comes in two sizes - 100mm and 150mm. Although the 150mm option doesn't provide significant lift yet, an update is on the way soon. Enjoy! Update 2: I modified the 150mm rotor file for improved performance. Update 3: Fixed files have been added to the package. Update 4: A short version of the key has been included for smaller buildplates. However, it hasn't been tested yet, so its effectiveness in allowing the toy to fly is unknown.
