FidgiGrip

FidgiGrip is an exThe FidgiGrip is a 3D-printed fidget toy designed as part of a rapid prototyping project. It incorporates three interactive features into an ergonomic grip, showcasing both functional and aesthetic considerations. The design process involved extensive research into existing fidget devices, iterative ideation through sketches, and detailed CAD modelling, primarily in Fusion 360. The prototype consists of eight parts assembled using friction fits, with no adhesives required, and was printed using PLA plastic.

Project Process

INSPIRATION

The FidgiGrip project drew inspiration from modern ergonomic tools and interactive fidget toys. The design aimed to combine multiple tactile elements into a single device that could engage the user in a meaningful way. The focus was on creating a compact, functional object that offered distinct interactions while maintaining a sleek and cohesive aesthetic. See the complete inspiration board here.

INITIAL SKETCHES

During the ideation phase, numerous designs were sketched to explore various forms and functionalities. These initial concepts focused on blending tactile features, such as a spin wheel and button, with an ergonomic grip. Some early designs emphasized minimalism, but they lacked the desired level of interactivity. Through refinement, a direction was chosen that incorporated multiple features into a single cohesive form.

CONCEPT REFINEMENT

Mid-Fidelity Models‍

After narrowing down the concept, the design moved into the digital realm, starting with basic 3D models in Shapr3D. This allowed for quick exploration of form and proportions. Key details, such as the angle of the grip and the placement of interactive components, were adjusted to enhance usability.

Final Concept‍

The finalized design was recreated in Fusion 360 with greater attention to detail. Features like the switch and spin wheel were fine-tuned to ensure proper functionality, while material constraints were considered to optimize the model for 3D printing. The result was a fully realized concept ready for prototyping.

PROTOTYPING & TESTING

The prototype underwent several stages of 3D printing to test tolerances and fit. Individual components were printed separately to refine complex parts like the spin wheel, while simpler elements like the shell were printed in their final forms. These iterations informed adjustments to dimensions and fit, ensuring a functional assembly.

FINAL PRODUCT

The FidgiGrip consists of eight components, assembled without adhesives using friction-fit connections. Post-processing included light sanding to ensure smooth surfaces and secure fits. The final model is a functional prototype that demonstrates the integration of design, ergonomics, and technical skill.
