What is the Bed Rocket?

The Bed Rocket is a 3D-printable, under-sheet cooling system designed to tuck neatly under the edge of your mattress. It funnels a steady stream of refreshing air directly between your top sheet and mattress, lowering your bed's temperature and eliminating trapped body heat for a perfectly cool night's sleep without needing to blast the AC.

💰 Premium Performance at a Fraction of the Cost

Commercial under-sheet cooling systems on the market will easily set you back anywhere from $200 to $500+ USD. By utilizing your 3D printer and an affordable, highly efficient fan, you can build the Bed Rocket V3 for a tiny fraction of that cost while getting the exact same elite cooling performance!

Upgraded from the Ground Up based on Community Feedback!

The Bed Rocket V3 is here, completely redesigned from scratch to incorporate your amazing ideas and deliver the ultimate bed-cooling experience.

Best of all, this completely overhauled version is now fully compatible with the Bambu Lab A1 mini. It is engineered to use the exact same 4" Inline Booster Duct Fan as V2, making it an incredibly easy and powerful upgrade if you are moving up from the previous version!

What’s New in V3:

• Weighted Base + Locking Nut: No more worrying about accidentally kicking the unit over in the dark. The new base is designed to perfectly fit a standard 1-inch, 5lb cast iron barbell weight (grab one on Amazon or use one you have lying around) and secures firmly to keep the V3 rock-solid and completely upright.
• Improved Housing Body: A sleek, unified body redesign that maximizes print durability while significantly optimizing internal airflow through the unit.
• Integrated Safety Grate: Built right below the intake fan, this new integrated guard keeps curious pets and little fingers completely safe from the fan blades.
• Vent Cover (Air Diffuser): Easily one of the most requested features from V2. I’ve added a sleek diffuser to the end of the duct so the air now disperses evenly and comfortably under the sheets, preventing a single harsh stream of air.

3 Ways to Use Your Bed Rocket V3:

You can easily customize your cooling experience depending on how you assemble the output:

1. Without Locking Exit Vent: Best if you want a more powerful, direct, single stream of concentrated airflow.
2. With Exit Vent: Provides a milder, slightly scattered airflow so it's not a single, intense concentration of air hitting you all at once.
3. With Vent Cover: Offers a wide disbursement of air to evenly spread out the flow comfortably across the entire bed, though it does slightly reduce overall air power.

⚠️ Important Notes:

1. Tight Fit for Safety: The tolerance when sliding the fan into the housing and coupling is deliberately tight to keep the fan completely secure. For the easiest assembly, place the housing body flat on the ground and apply firm, moderate downward pressure when sliding the fan in.
2. Assembly Video: A full assembly video is coming soon to guide you through the setup process step-by-step!
3. More to Come: Additional stability accessories and add-ons are already actively in development… Stay tuned!
4. Now fully compatible with the Bambu Lab A1 mini (and larger printers).

Required Parts:

• 4" Inline Booster Duct Fan
