🛠️ Product Description
Bring professional‑grade Korry pushbutton indicators to your home cockpit with this complete 389 Korry v1 CAD & STL package. Designed for high accuracy and compatibility, these models complement the physical 389 Korry PCB, available here:
🔗 https://www.737diysim.com/product-page/dual-colour-korry-replica-pcb
This download includes both the PCB‑compatible version and the earlier non‑PCB variant, where tactile LED switches press directly into the inner housing for hand‑soldered builds. Although most builders now prefer the PCB version for simplicity, the non‑PCB model remains ideal for beginners and budget‑conscious makers.
Carefully engineered to replicate the feel and function of real Korry units, these files allow you to print fully functional, dual‑colour or single‑colour indicator buttons at home — perfect for Boeing, Airbus, and custom simulator projects.
✨ Key Features
Dual‑Version Package
Non‑PCB Version: Push tactile LED switches directly into the inner case; excellent for first‑time builders.
PCB Version: Designed to match the official 389 Korry PCB for clean, simple assembly.
Multiple Housing Types
Dual‑Colour (Split Top/Bottom)
Single Dual‑Colour Lens Option
Single‑Colour Case (one‑colour captions)
Korry Cage Included
A robust mount option for securing the Korry to your panel — stronger and more stable than grub‑screw alternatives.
Home‑Printable Design
Optimised for resin printers, producing smooth surfaces and clean button travel with no layer artifacts.
Filament printing supported (e.g., Bambu P1S) with minor tuning.
Tight tolerances preserve the crisp operation and click‑feel of the real unit.
Lens Compatibility
Laser‑etched lenses fit perfectly into the housing.
Standard single‑design lens included (ideal for filament users).
