How I Built the Severance Speaker (and Took It to the Real Lumon Building)

"Hey there, you on the table!"
If you’re a Severance fan, you know exactly what that means. This eerie, minimalist speaker sits on the Lumon boardroom table… and I just had to bring it into the real world.
In this build, I walk through the entire process—from 3D printing and laser cutting to painting, electronics, and yes, even sneaking a camera inside. Then, I took it to the real Lumon HQ (aka Bell Works in New Jersey) to see what people would do when they heard that familiar voice.
If you're ready to build your own Severance speaker, here's everything you need to know.

🛠 Step-by-Step Build Guide
Step 1: Find the Model
Start by grabbing the highly accurate 3D model from Kiwi Models on Etsy. It’s screen-accurate and will save you hours of modeling time.
Step 2: Print the Body
Print in PLA with thicker-than-default walls for strength. It may take a couple of tries depending on your printer’s quality. The frame should be clean, sturdy, and ready to sand.
Step 3: Laser Cut the Grill
I couldn’t get the grill detail I wanted with a 3D print, so I:
Took a flat image from the model
Vectorized it in laser software
Test cut in craft paper
Final cut on basswood ply
The grill fits snugly inside the front recess—just like the show.
Step 4: Prime & Paint
Spray all components with primer first. Then:
Coat the grill in truck bed liner for texture
Use adhesion promoter so your color coat sticks
Paint grill blue, body off-white (like Bakelite)
Check the show stills—Severance uses a subtle but distinct '70s palette.
Step 5: Smooth the 3D Print
Since this prop had to look brand new, I filled in print lines with putty, sanded smooth, and did several layers of priming and sanding. Patience is key here.
Step 6: Add Electronics
Install a DFPlayer Mini inside, wired to a push button and small speaker. Upload Severance quotes to the MP3 player via microSD. You can trigger playback with a discreet button in the back panel.
Optional: add a small spy cam to record interactions.
Step 7: Final Touches & Assembly
After paint is fully dry and electronics are installed:
Fit the grill into the front recess
Secure the back panel and shave any raised print tabs
Test your speaker playback
Then… take it somewhere cool (like I did).
🏢 The Real Lumon Building
With the speaker finished, I took it to Bell Works in Holmdel, NJ—the real-world filming location used for Lumon HQ. Wearing my Macrodata Refinement badge and holding the speaker, I strolled through the iconic walkways, triggering audio quotes from Mark S.
Yes, people noticed.
