The model was created in Autodesk Inventor 2011, using only 90 degree angles to maintain its rigid appearance. It was designed to stand up on a desk or computer, and was inspired by the increasing popular game called Minecraft. Additionally, the design was meant to test the makerbot. The Creeper is a close to exact scale model of the one in the game. It was supposed to have 4 legs instead of 2 but I decided to have 2 because it would be more structurally strong.
Due to the laws of physics, the original print didn't turn out exactly as i wanted it to. As you can see by the attached images, the mouth sagged a bit because the Makerbot was forced to extrude the plastic in mid air (as it prints layer by layer). I then refined the original design to prevent this from happening by increasing the width of the bottom of the mouth.
Since the Creeper is only one part, the instructions are fairly simple.
- Download the STL file.
- Generate the G-Code for the part.
- Print the part
- Remove from platform and enjoy!
