This model is a purpose‑designed case system for the new v4 Korry SMD PCBs used in Boeing‑style and many other cockpit simulator builds—especially the upcoming next‑generation 737DIYSIM overhead. These PCB can be found here:

The design includes all 3D‑printable case components plus the CAD files needed to ensure perfect tolerance matching across different printers and materials.
The enclosure was engineered specifically to house the new dual‑sided SMD PCB layout, which features dual ALPS switches, SMD LEDs, and a redesigned connector arrangement. These cases securely hold the PCB, centre the switch press, maintain correct lens alignment, and replicate the real Korry feel and geometry as closely as possible.
 
Use & Purpose
This case system is essential for anyone using the v4 Korry SMD PCBs, as the new PCB footprint, depth, and mounting points are not compatible with older enclosures. The model ensures:
Perfect PCB fit for the v4 design
Stable switch action thanks to internal support geometry
Correct lens alignment and light distribution
Drop‑in installation within 737‑style overhead panels
Long‑term durability, even with frequent tests or button presses
Builders can choose resin printing for maximum surface detail and accuracy, or FDM/filament printing, which also works extremely well due to built‑in tolerances.
 
Originality & What Makes It Essential
This design is a complete overhaul from previous Korry case versions.
What makes it unique:
Created exclusively for the new v4 SMD PCB series
Includes adjustable CAD files to account for cross‑printer variance
Uses real‑aircraft‑inspired proportions for an authentic appearance
Strengthened internal geometry for long‑lasting tactile performance
Supports all three Korry modes:
Caption only
Press‑to‑test
Full caption + press‑to‑test + functional switch
The case is not a remix of any other model—it's an original 737DIYSIM design built from scratch around the electrical and mechanical requirements of the new PCB.
 
Limitations & Notes
These cases must be used with the v4 SMD PCBs—older PCBs will not fit.
Some builders may need to tweak tolerances depending on printer calibration.
Resin printing gives the best results; filament printing works very well too.
Caption lenses are not included—they are available separately.
Not recommended for beginners unless familiar with installing small PCBs and tactile switches.
