A Contest That Will Make Your 3D Motors Vibrate

Prusa Research and CMF have launched a challenge that will test the creativity of the maker community: designing modular accessories for the CMF Phone 2 Pro. Participants have 22 days to submit up to five ideas, enough time for any 3D enthusiast to go from "I have a great idea" to "why isn't this working?" several times. 🚀

Creative Freedom with Screws Included

The phone in question comes with a particularity that will make any designer happy: visible screws and a universal connector. This means you can create everything from stands to crazy accessories without needing to solder or open the device. It's like playing with LEGO, but for adults who prefer filament to toy plastic.

"It's the perfect opportunity to prove that your modeling skills are good for more than just printing little figures" - said no contest organizer, but they should have.

Prizes That Will Make Your Eyes Shine

The lucky winners will be able to take home:

Why This Contest is Different

CMF has provided CAD files with all the necessary measurements, thus avoiding the classic "let's measure with a ruler and pray." This allows even those who don't have the phone to participate, ideal for those designers who spend more time in Blender than in the real world. 🖥️

Furthermore, the contest follows the modular design trend that is revolutionizing the way we interact with our devices. Instead of buying accessories, you print them at home, which is great until you realize you've spent more time designing than using the phone.

Tips to Stand Out from the Crowd

If you want to impress the judges, consider:

Remember that the goal is not to create the accessory with the most polygons, but the one someone would actually want to use. Unless, of course, your design is so cool that people are willing to change pants just to carry it with them. 👖

So now you know, if you need an excuse to spend hours in front of the computer saying "I'm working on an important project," this is your moment. And if you don't win, you'll always have the consolation of having created something unique... or at least of having tried not to burn the printer in the process. 🔥
