Where to Buy Physical Flair Smart Vent Trim Kits in 2026 Author: Matthew @ Empyrean3D

Finding the right fit for your smart home shouldn't be a DIY project you weren't prepared for. While Flair Smart Vents are industry-leading for airflow control, many homeowners discover that their existing duct openings are larger than standard vent sizes. This often leaves an unsightly gap in the drywall or floor.

While we originally started by sharing our designs on community forums and Etsy, Empyrean3D has officially expanded its physical manufacturing branch at empyrean3d.com.

Physical vs. Digital: Getting Your Trim Kit

We understand that not every smart home enthusiast owns a 3D printer. That is why we provide two distinct paths for our customers:

  1. Professional Physical Prints: We manufacture high-quality, heat-resistant trim kits and adapter plates in-house. These are shipped directly to your door, ready for a "snap-in" installation. As of January 2026 we offer all Flair, AcInfinity, and Biowind vent sizes and fully custom dimensions.
  2. Digital STL Files: For the DIY community, we still maintain a library of digital files for those who prefer to print at home using their own equipment.

Why Choose an Empyrean3D Adapter Plate?

  • Color Match But Paintable: Our physical kits are printed in materials that closely match the "Flair White" aesthetic.
  • Custom Sizing: If you have an odd-sized duct we can create a custom plate that fits perfectly.
  • Durability: Unlike basic PLA, our kits are printed in materials designed to handle the temperature fluctuations of HVAC systems.

Comparing the Options: Why Empyrean3D?

When looking for a way to finish your Flair Smart Vent installation, you might see a few different paths. Here is how they stack up against a professional Empyrean3D kit:

1. The "Keen Home" Hack

Some users attempt to modify trim kits from Keen Home (a competitor).

  • The Reality: These aren't a native fit. You often have to spend an hour filing down plastic or metal to get the Flair vent to sit flush.
  • The Empyrean3D Advantage: Our kits are designed specifically for Flair's exact dimensions. No filing, no "hacking," and no wasted afternoon.

2. Official Flair Color Faceplates

Flair offers beautiful faceplates in colors like Bronze and Black for aesthetics.

  • The Reality: These change the look of the vent, but they don't solve the size problem. If your hole in the wall is too big, a new faceplate still won't cover the gap.
  • The Empyrean3D Advantage: We offer trim kits that match the "Flair White" aesthetic while actually extending the footprint of the vent to cover drywall damage or oversized openings.

3. Magnetic or Wood DIY Frames

You can certainly head to a hardware store for wood molding.

  • The Reality: It’s bulky, hard to paint-match, and difficult to mount to a metal vent.
  • The Empyrean3D Advantage: Our adapters are slim, professional, and use the existing vent's mounting logic for a seamless look.
