Follow these simple steps to attach a 3D-printed ergonomic handle to your RG477M retro handheld. Improve comfort and control in minutes.
Quick answer
Attach the custom handle by aligning it with the RG477M's back panel and snapping it into place. No tools or adhesives are needed.
Why add a custom handle?
The RG477M is a compact retro handheld, but extended play sessions can cramp your hands. A custom handle adds an ergonomic contour that lets you grip the device more naturally, reducing fatigue and improving control.
The handle is 3D-printed from PLA plastic, making it lightweight (62 g) yet sturdy. It clips on without modifying the console, so you can remove it anytime.
Installation steps
- 1. Power off and inspect: Turn off the RG477M and remove any case or grip already attached. Check that the back panel is clean and free of debris. A clean surface helps the handle grip securely and prevents scratches.
- 2. Align the handle: Hold the custom handle with the curved side facing the console's back. Line up the mounting tabs on the handle with the corresponding slots on the RG477M's rear edge. If it doesn't align easily, rotate the handle 180° – the tabs are asymmetrical.
- 3. Snap into place: Press the handle evenly onto the console until you hear a soft click. Start from one side and work your way across to ensure even pressure. Avoid forcing it. If resistance is high, double-check alignment rather than pushing harder.
- 4. Test the fit: Hold the console normally and check that all buttons, triggers, and ports remain accessible. The handle should not block the headphone jack, USB-C port, or shoulder buttons. If a port is obstructed, remove the handle and re-seat it slightly lower or higher.
- 5. Remove and store when not in use: To detach, gently pry one corner of the handle away from the console. The PLA plastic flexes slightly, so it won't break with careful handling. Store the handle in a dry place to avoid warping. Avoid leaving it in direct sunlight for long periods.
