Building Procedures and Pricing
We began with a detailed sketch of our product, and began modeling it in Autodesk Inventor. It took about a day to get our model fully designed, but we ran into some issues. We ended up changing the dimensions a bit to make the jar more efficient in the amount of peanut butter that it could actually contain. We also had to download a plugin for Inventor called coolOrange threadModeler that took our thread models and actually cut the threads out on our design.

Tools and Equipment
Estimated time to build: 6-8 hrs
Tools and Equipment needed: Autodesk Inventor Professional 2016, name of 3D printer we're using
Tools and Equipment needed: Autodesk Inventor Professional 2016, name of 3D printer we're using
Build Procedure
- Create the separate parts of the jar (top lid, jar, bottom lid) In Autodesk Inventor.
- Export the files to match those that the 3D printer uses/ runs on.
- Allow the 3D printer to create our product.
"In build" Refinements
While designing our product in Inventor, the group agreed to change the shape of the scraper. Our original shape which resembled the dorsal fin of a shark would have worked, however, to catch and hold the peanut butter more effectively we designed a rectangular scraper that would complete its intended purpose better.
Special thanks
We would like to thank Daniel Fischer, our adviser who helped us throughout the project with ideas and resources. It was his personal 3D printer that we used to prototype our product, so we would not have been able to prototype without him.
Documentation of Building Process
For our first prototype, we printed the jar and the bottom lid to test dimensions. I'm not sure if we underestimated the thickness of the plastic or if something got messed up from our computer program to the program of the 3D printer, but our scrapers were right up against the sides of the bottom lid so we couldn't fit the jar into the threads. Also, the inside diameter of the jar was the same as the inside diameter of the lid, so we couldn't fit the jar into the lid even without the scrapers.
