Bed Rocket: V2 (Bed Cooling System)

Boost MeBoost me and I'll make additional accessories for free! (Think air diffusers & more!) Thanks to the community for all the feedback!

 

Stay cool all night with Bed Rocket V2—a powerful, budget-friendly alternative to expensive bed cooling systems. This upgraded version uses a 4" Inline Booster Duct Fan to deliver a strong, adjustable stream of air directly under your sheets—perfect for hot sleepers or warm nights.

 

The redesigned vertical duct system channels airflow efficiently through custom tubing and a compact vent, giving you a consistent cooling breeze where it matters most.

Why Bed Rocket V2 is better:

• High-Speed Airflow: Powered by a 4" Inline Booster Duct Fan with adjustable speed, giving you full control over your cooling.
• Massive Performance Boost: Blows up to 137% faster than Version 1 for noticeably better airflow under the covers.
• Budget-Friendly: Competing systems cost $200-$500+ USD. This setup uses around 700g of filament and a fan under $30 USD.
• DIY Friendly: Fully 3D printable and adaptable to different bed heights for a perfect fit.

Skip the overpriced gadgets and complex electronics - Bed Rocket V2 keeps it simple, effective, and cool.

 

UPDATE

8.13.25: Thanks so much for all your support and suggestions, I appreciate every one. I’m actively designing V3! This overhaul will focus on better stability, safety, and more even/disbursed airflow, as well as some highly requested attachments. For the most part, everything should be compatible with V2, so don't worry about having to print it all out again. Got ideas? Drop me a message, I’d love to hear them! And keep the boosts coming—they keep me motivated to make it happen!
