We’ve teamed up once again with Printables.com for a complex design challenge!
This time, you’ll get to choose from three different modular products to make your own.

Cooler Master’s FreeForm 2.0 philosophy is all about giving makers the tools (and permission) to experiment, remix, and reimagine hardware their own way. With the MasterFrame 600, Qube 540, and Atmos II, you’ve got three different canvases for your creativity — pick one and you can start designing!

Want to improve functionality, enhance aesthetics, or completely rethink a part? Let’s see how far you can take the FreeForm idea.
