ENTR 390 - 3D Printing/Prototyping

My  ergonomic mouse targets those who use computers extensively, especially those with carpal tunnel or larger hands who need better wrist support and comfort. Unlike standard symmetrical mice, this design features a sculpted vertical shape that elevates the palm and redistributes pressure to reduce strain on the wrist. I began with a simple block and gradually carved the form to follow the natural contour of the hand, adding grooves to guide finger placement and clearly define the buttons. These grooves were created using pipe cutouts, which helped shape the buttons in a way that increases visibility. To enhance usability, I added extruded buttons for sensitivity adjustment that can be easily accessed without moving the hand. A hexagon feature was embossed to house a customizable light that can indicate battery level or be personalized through an app, which would also allow users to control lighting colors and sensitivity levels. Overall, this mouse is designed to combine ergonomi...

  My ergonomic mouse is designed for people who use computers often, especially those with carpal tunnel or larger hands who need a more comfortable fit. It combines the shape of an ergonomic mouse with the style of my personal mouse and features easily accessible buttons to adjust sensitivity, along with a light that shows battery life or charging status in any color the user chooses. To make it better, I could add adjustable angles or a textured grip for even more comfort during long use. People definitely care about this because comfort, customization, and usability are important for anyone working or gaming for hours. It’s also marketable since users can connect it to a mobile or desktop app to personalize sensitivity levels and lighting, making it both functional and customizable.

The ring I created is meant to symbolize marriage and usually has sentimental or monetary value depending on the material. The hardest part of working with T-Splines was making sure the prong faces didn’t overlap, since that would’ve caused errors in the model. If I had more time, I’d subdivide the prongs to make them rounder and add more detail to the stone so it looks more realistic.

When designing my phone holder, I had to make trade-offs due to the 100mm x 100mm x 20mm bounding box constraint, which required me to reduce the overall length of the stand. In addition, based on my current capabilities, I was unable to implement the full range of rotational adjustments I originally planned for. Despite these compromises, I kept the design focused on user needs, such as ensuring the phone can rest securely, allowing for hands-free use in cooking, studying, or content creation. I prioritized a sturdy angled support with openings for both flashlight projection and camera recording, aligning with real-life tasks like following recipes or filming tutorials. If I had more time and tools, I would improve the base stability and add detachable rotation joints. Overall, the design reflects a balance between feasibility under the given constraints and the design's goal of enhancing everyday convenience for multitasking users.

This soap holder is designed specifically for bars of soap used near sinks. Traditional soap holders often fail to drain water effectively, leaving soap to sit in pooled moisture. As a result, the soap softens, sticks to the holder, and can even promote mold growth if there are no drainage holes. This design addresses those issues by angling the soap slightly toward a front drainage hole, allowing excess water to flow directly into the sink for faster drying and improved hygiene.

  As a student who enjoys cooking and baking with recipes, I often struggle with having to pick up my phone when my hands are messy or full. That’s why I sketched a phone holder. The product is height-adjustable and includes a rotating head and detachable pieces, which allow for multiple viewing angles and easy disassembly for storage. These features make it versatile, and additional improvements like a sturdier base and arms or a washable surface could further enhance its functionality in home environments. From following recipes without smudging your phone, watching videos comfortably, recording hands-free content, or even using the phone flashlight for repairs without needing (to make your sister hold it) a second person to help, the product aims to solve some of the everyday frustrations that normal people have. A phone holder is marketable because it appeals to a broad audience—students, content creators, home cooks, and anyone who just needs a convenient way to view their ph...
