CoolerMaster Qube540 PC case accessory - filament dryer/heat recycler

Recycle that heat from your extra FPS and FLOPS!

Why let all that precious CPU and GPU heat go to waste? This printable duct and spool mount turn your PC case into a mini filament dryer — no extra electronics, no power draw, just pure thermal recycling.

Warm exhaust air is gently guided to your filament spool, keeping it dry and ready to print. Your rig stays cool, your filament stays dry, and your energy bill stays exactly the same.

It’s sustainable, functional, and just the right amount of ridiculous.

So next time your CPU hits 90°C, just smile and say: 

“It’s not overheating… it’s preheating my PLA.”

For better printability, it has no integrated clips, just placeholders to glue or press-fit the mounting hole clips provided here: https://www.printables.com/model/1465171-qube-540-full-pc-case-step-model-3d-printing-base/files

For less friction, you can use a bit of PTFE tube inserted into placeholders on top of SpoolRoller.
