Additive Manufacturing: Geometric Fidget

The goal of this project was to design a product in CAD that could only be produced using additive manufacturing (3D printing) but would never actually be printed. My design focused on a geometric fidget toy, where the key challenge was to create a product that was optimized for 3D printing without the need for traditional manufacturing methods.

I began by exploring different 3D solids, narrowing down the design to a dodecahedron due to its unique geometric properties and suitability for intricate, additive manufacturing-specific features like hollow spaces and interlocking parts.

Technologies Used

The design was created using advanced CAD tools, focusing on the potential of 3D printing to bring to life a product that traditional manufacturing methods could not replicate. Key tools and technologies used:

Onshape

3D Modeling and Design, Production Drawing Creation

Cura Slicer

3D Slicer Software for Prototyping (Weight, Size)

3D Printing (Prusa Mini)

Prototyping Material (Conceptual)

Project Timeline

Initial Concept & Design

The project began with research into geometric shapes and prototyping methods. I decided to focus on the dodecahedron as the base form for the fidget toy.

First Prototype

Using Onshape, I developed the first 3D model of the fidget toy, focusing on creating a mechanism for rotation and tactile interaction.

Testing & Iteration

The first prototype was simulated in CAD, and several iterations followed to improve ergonomics, aesthetics, and functionality for additive manufacturing.
