My coworkers gave me the challenge of 3d printing something Medieval related. I decided to make a Catapult with the added challenge of making it really fire.

I designed the catapult as a series of pieces that could be printed separately and attached together.

05 - Front Angle in Blender

 

Here's some orthogonal views:

While designing the model I kept in mind the way each piece would be printed and built them so the printer would have an easy time. I laid all the required parts out for 3D printing:

And finally I printed it! Scroll to the bottom for a quick video of the catapult in action!
