3D model description:
 
This is a 737SS DU panel file pack created for builders who want a clean, realistic illumination result—especially in low-light environments.
Unlike many DU panel designs that place rotary switches on the faceplate (often causing hotspots, uneven diffusion, or dead zones), this panel relocates the rotary switches away from the faceplate to support more consistent light spread to the knobs. That means:
More even backlighting across the panel
Knob stripes that actually glow at night
A cleaner, more “finished” look when installed in a home cockpit
It’s an ideal solution if you care about night lighting realism, where tiny details (like knob index illumination) make a big difference in immersion.
 
✅ What’s included (digital files only)
You will receive digital design files only (CAD + 3D-print-ready assets). No physical items are shipped.
Not included: displays, LEDs, wiring, switches, fasteners, or any electronics.
 
✅ Context of use (how it’s used in a build)
This DU panel is intended for a Boeing 737-style home cockpit / simulator MIP setup, where the panel is backlit and installed as a self-contained unit using the integrated back box concept.
Lighting approach (recommended)
Panel backlighting: 12V LED strip (warm white preferred)
The back box helps form a tidy, enclosed lighting cavity for consistent illumination
Knob illumination method (important)
For best results, print knobs in clear resin, then:
Paint grey
Sand the raised stripe to remove paint from the line
Optionally, leave the stripe clear or paint it white
This technique allows the index stripe to glow convincingly at night.
✅ Compatibility (switch support)
This design is made to work with:
Larger 8-position rotary switches
Smaller, more affordable “sr16” rotary switches are commonly available
 
⚠️ Potential limitations / what buyers should know
Digital files only: you must 3D print and source all hardware/electronics yourself.
Best knob results require resin: FDM can work for some parts, but clear resin is strongly recommended for glowing knob stripes.
 
Lighting outcomes depend on build choices: LED type/placement, diffusion, paint thickness, and resin clarity affect brightness and uniformity.
 
Switch sourcing varies: verify the exact dimensions/pin style of your chosen rotary switches (8-position vs sr16 variants), as off-brand tolerances can differ.
 
DIY skill level: expect typical home cockpit work—finishing, light-sealing, sanding, painting, and wiring for lighting.
