This listing offers a cost‑effective version of the 737SS Dummy RMI (Radio Magnetic Indicator) designed for builders who only need the 3D‑printable files and not the full CAD package. It’s the perfect lightweight option for anyone wanting to complete their 737SS MIP visually while keeping costs down. ✔ What’s Included

3D‑print‑ready 3MF files only (No CAD source files, no editable models)

The model consists of two print‑friendly parts, designed for easy assembly and a clean, realistic finish. ✔ What This Dummy RMI Is This is a non‑functional fascia that replicates the appearance of the real 737 RMI unit. When paired with ProSim, the RMI’s digital display can be repositioned behind this frame on the MIP—creating a fully visual, working‑style gauge without additional screens. ✔ Why It’s Useful This budget version is ideal for builders who:

Don’t need the CAD files Want a fast, ready‑to‑print solution Are completing their 737SS MIP visually Prefer a realistic look without extra electronics

Because the RMI display is digitally moved in ProSim, no HDMI or USB ports are needed, and no separate LCD screen must be installed. The frame is set to match the exact depth of the MIP, creating a seamless, authentic look.

✔ Optional Enhancements For a professional finish, you can add:
