Affordable. Print‑Ready. Backlight‑Capable.
Bring authentic C172 functionality into your home cockpit at the lowest cost with this STL‑only edition of the 737DIYSIM C172 Avionics Switch Panel. Designed specifically for FDM 3D printing, this panel features enlarged, highly readable text and clean layout proportions—ensuring crisp, professional‑looking results on almost any hobby printer.
 
This version includes only the STL files, making it the perfect choice for builders who simply want to print and install the panel without the need for CAD editing or modifications.
 
🛩️ Optimised for High‑Quality 3D Printing
The panel has been adapted to ensure the text and linework print cleanly with standard nozzle sizes and typical printer tolerances.
Oversized lettering for sharp, clear legends
Slightly enlarged panel footprint for better print aesthetics
Clean geometry tailored for FDM extrusion behaviour
 
💡 Backlighting Compatible
Like the premium version, this budget STL pack supports 12V LED backlighting:
Multi‑colour printing allows the white legend layer to pass through the panel for a bright, even glow
Single‑colour printers can produce a clean look by printing white text on a grey base without using backlighting
