Bored of pointless 3D printer projects? Out of 3D printing ideas? Check out our February 2019 list of cool things to 3D print which are actually useful.
Like us, you’re tremendously excited by the possibilities of 3D printing. Unfortunately, the landscape is cluttered with trinkets, doodads, and ornaments. We’re in danger of drowning in 3D printed objects that nobody wants or needs.
Fight the tide of mediocrity! Let’s make stuff that’s useful! Here’s a list of cool things to 3D print, right now, today. Prove to your nearest and dearest that there’s an everyday and practical application of this wonderful technology.
Updated monthly under the guise of our very own printocracy, each month we remove the five least clicked models and replace them with five new printables. As the year trudges on, there will always be something new, and the uninteresting items drift away. Simple!
Brighten up your home with this funky printable. Derived from Harvhammas’s original Nanoleaf Light Panel Replica, this smart version improves on the software for controlling the LED lights, alongside detailed instructions and a large number of printable parts for configuring the setup as you need it.
