3D model description

Bring your 737SS simulator build to life with this highly detailed Dummy RMI (Radio Magnetic Indicator) Frame—a visually accurate reproduction designed specifically for home cockpit builders. This model has been engineered with precision and practicality in mind, making it an ideal addition to the 737SS Main Instrument Panel (MIP).
✔ What This Creation Is
This package contains the CAD design files (PDF) and 3D‑print‑ready 3MF files required to print a realistic RMI dummy unit.
The model is split into two main 3D‑printable parts for clean assembly and a crisp, professional finish.
This is a non‑functional RMI—created as a fascia to replicate the appearance of the real instrument while integrating seamlessly with ProSim.
✔ How It Works in a Simulator
Instead of installing an additional LCD behind the unit, the ProSim RMI display is digitally repositioned to the same location on the MIP. This approach:

Avoids extra USB or HDMI ports
Eliminates the need for additional monitors
Keeps wiring simple and reliable
Matches the depth to the MIP thickness, creating a realistic transition that makes the dummy frame look like a working instrument

Perfect for the 737SS when you want visual authenticity without adding more screens.

✔ Originality & Why It’s Essential
This RMI dummy frame solves a common problem for home cockpit builders:
How to include the standby RMI visually without adding extra screens, cables, and power?
Its custom‑fit geometry, accurate proportions, and ProSim‑friendly workflow make it:

Ideal for compact cockpits
Great for builders prioritizing realism with minimal electronics
Essential for completing the authentic 737SS MIP layout

✔ Context of Use & Limitations

This is a visual dummy unit only—no electronics or internal display are included.
The RMI digit is repositioned in ProSim to align with the dummy frame on the MIP.
Package includes 3D printable parts only (CAD PDF + 3MF).
For the most polished result, consider the lens and knobs linked above.
