We\u2019ve teamed up with HyperX to bring you a new design challenge! This time, it\u2019s all about a gaming mouse that\u2019s not just for gamers.

\r\n\r\n

The HyperX Pulsefire Saga is a new wired and wireless gaming mouse with something unusual under the hood: it\u2019s designed from the ground up to be modular and 3D-print friendly. You can swap out the shell, redesign the buttons, or rework the entire outer shape. HyperX even released official STL and STP files on Printables so anyone can jump in and start customizing.

\r\n\r\n

Whether you're into gaming, productivity, accessibility tweaks, or just love making hardware your own \u2014 this mouse is a great blank canvas.

\r\n\r\n

Check out the official HyperX page to learn more about this mouse, its features, and how it was made for customization.

\r\n\r\n

The Challenge

\r\n\r\n

Download the official files, remix the design, and upload your own 3D-printable parts for the Pulsefire Saga or Saga Pro. That could mean:

\r\n\r\n

A new top shell with a different grip style
Ergonomic improvements
Fun or artistic remixes
Add-ons that give the mouse new features or flair

\r\n\r\n

The mouse was built to be modular \u2014 shell and button files are ready for printing, testing, and remixing. You don\u2019t even need to own the mouse. Print the chassis, fit your design, and show what\u2019s possible.

\r\n\r\n

Resources

\r\n\r\n

All the files you need \u2014 in both STL and STP formats \u2014 are available right here on Printables. You\u2019ll find exact dimensions and printable chassis parts so you can design with confidence, even without owning the mouse.

Challenge

\r\nEver looked at your pet and thought, \"You deserve something awesome\"? Well, now\u2019s your chance to fix that! Design a tech-powered gadget for your furry (or non-furry) friend using Arduino and 3D printing. Think automated playmates, high-tech trackers, smart aquariums, or remote-controlled feeders. Whether it\u2019s a self-fetching ball launcher, a next-level scratching post, or a fish tank that runs itself\u2014you know what your pet needs.\r\n
\r\n
\r\nNever used Arduino before? No worries! Arduino is a small, programmable board that can control lights, motors, or sensors, and it\u2019s the perfect way to add some tech magic to your project.\r\n
