We built a fully Open-Source, Smart Enclosure with Air Filtration & Filament Tracking - Now live on Kickstarter

Hey fellow makers! 👋

By day, we’re a group of aerospace engineering students at TU Delft, but by night, we’re makers who have been in the 3D printing space since 2016.

Like many of you, we’ve always struggled with one existential problem: the air quality in our workspaces. We noticed that printing with materials like ABS, PETG, and even PLA releases fumes, ultrafine particles (UFPs), and VOCs that linger in the room. We searched for a solution, but most enclosures on the market were either niche to specific printers, sacrificed build quality, or were simply too expensive.

So, we decided to build our own. Meet Clura—a modular, smart, and completely open-source 3D printer enclosure.
This awesome project is now live on kickstarter (fully funded in 58 minutes!)

We wanted to create something that actually protects your health while optimizing the printing process. Here is what we integrated into the design:

• Air Filtration: It uses high-performance fans with dual-layer HEPA and carbon filtration, capable of filtering the entire enclosure volume in just 60 seconds.

• Smart Sensors & Fire Safety: We packed it with a dedicated sensor suite. It uses a BME680 for temp/humidity/VOCs and a PMS5003 for particle tracking. For safety, it combines an MQ2 gas sensor with MEMS and optical smoke sensors to detect thermal runaway or fires instantly.

• Filament Weight Tracking: We integrated HX711-based load cells into the spool holders to track filament weight in real-time. No more guessing if you have enough plastic to finish a print!

• Universal Fit: Because it's modular, it currently fits the Prusa MK3/MK4, Bambu Lab A1/Mini, Prusa Mini, Ender 3 style bed slingers and so much more...

Our 100% Open-Source Promise We are firm believers in the open-source community. Every CAD file, software component, and build guide is free and released under the CC BY-NC license. (links on docs.clura.dev) You can self-source the parts and build it yourself, customize it, and even submit your own mods to our Community Upgrade Center. You own it completely. No vendor lock-in, ever.

The kits we offer are just a convenient way to assemble it by supporting the project while saving time and money in the process.

We'd love to hear your feedback! Happy printing! 🛠️
