3D Design Contests

For this one, we’ve joined forces with CMF by Nothing — a tech brand that puts modularity and playful design at the core of its products. The contest is all about their new CMF Phone 2 Pro : a phone with visible screws and a universal adaptor. It’s designed to be customized — and it’s ready for the Printables community to take over! Challenge Design a back cover, add-on, or accessory that changes how the CMF Phone 2 Pro can look, feel, or function. Maybe it’s a smart new way to carry the phone, a module that adds entirely new features, or simply a visual twist through color, pattern, or texture. Functional, playful, strange, or minimal — whatever direction you take, we can’t wait to see ideas that make tech fun! Don’t have the phone? That’s totally fine! You don’t need the CMF Phone 2 Pro to take part — we’ll provide all the files, dimensions, and details you need to design here . Please note: this contest is all about custom accessories made specifically for the CMF Phone 2 Pro. General-purpose phone stands or unrelated designs won’t be eligible — we’re looking for ideas tailored to this device.

Gardens have already woken up and watering gear is making its way out of storage — and anyone who’s ever wrestled with a tangled hose knows the value of a setup that actually works! This flash contest is all about practical, 3D-printable tools that make working with garden hoses smoother, tidier, or just less frustrating. A wall-mounted clip, a quick adapter, a sprinkler stand, or a guide that keeps your hose from crushing the flower beds — even small upgrades can make a big difference for the home gardener. Share your smart solutions for hose storage, flow control, and everyday watering.

Stamps and seals have been around for thousands of years — once carefully carved from stone, metal, or wood to leave a personal mark. Today you can design and create your own in just a few hours! In this round of flash contest, you can create a functional stamp or seal — whether it’s a simple handheld design or something more mechanical, like a self-inking stamp. It can leave an ink impression or press a raised pattern, as long as it’s ready to use. If you want a few quick tips before starting, check out our blog post How to 3D print stamps .

We’ve teamed up with HyperX to bring you a new design challenge! This time, it’s all about a gaming mouse that’s not just for gamers. The HyperX Pulsefire Saga is a new wired and wireless gaming mouse with something unusual under the hood: it’s 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. Whether you're into gaming, productivity, accessibility tweaks, or just love making hardware your own — this mouse is a great blank canvas. Check out the official HyperX page to learn more about this mouse, its features, and how it was made for customization. The Challenge Download the official files, remix the design, and upload your own 3D-printable parts for the Pulsefire Saga or Saga Pro. That could mean: 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 The mouse was built to be modular — shell and button files are ready for printing, testing, and remixing. You don’t even need to own the mouse. Print the chassis, fit your design, and show what’s possible. Resources All the files you need — in both STL and STP formats — are available right here on Printables . You’ll find exact dimensions and printable chassis parts so you can design with confidence, even without owning the mouse.
