We're excited and proud to launch Thingiverse Apps. Learn More about what this means to you.
Here is a rendition of a truck/catapult combo.
The idea started when we bought a wooden toy from the hardware store that had to be glued and hammered together.
From scratch, we created the following design-enjoy!
You can read more about it at http://airwolf3d.com/blog/2012/10/16/download-and-3d-print-our-functioning-catapult/
Slice the stl file with your favorite slicer-we run one outer perimeters at 100mm/s and use 35% fill with Slic3r.
Note: Â No support is necessary if you have decent bridging ability. Â
Be careful not to hurt yourself or anybody else - this a tough design that can launch items up to 20 feet!
