1. Define the Problem

Use the design process to design, document, and create a 3D printed model of a posable figure utilizing snap fits and interchangeable parts

2. Generate Concepts

Using a decision making matrix to achieve a data driven solution to for the best design of a snap fit by taking the emotion out of decision making

3. Develop a Solution

Using a Gantt chart to create a plan to accomplish the goal in 10 days.  Section and detail views ensure that all parts will fit together with an acceptable tolerance.

4. Construct and Test a Prototype

Prototypes are first modeled in Autodesk Inventor before 3D printing resulting in a shorter design cycle that allows more iterations to reach the best solution

5. Evaluate the Solution

Problem #1:  The biggest problem was the pegs breaking off.  I tried several things:

  • increasing infill density

  • adding a fillet at break point 

  • using Makerbot's "tough" PLA instead of their standard PLA

 

Problem #2:  The person also wasn't stable​.  I remedied this by:

  • printing larger feet that snap fit onto the exiting rectangular feet

 

Problem #3:  The person didn't serve a purpose:

  • added some holes so that it could hold pencils​

6. Present the Solution

This is  the final prototype of the 3D printed posable figure.  It was printed on a Makerbot Replicator using tough PLA.
