Wii light gun grip and sights

thingiverse

Simple Wii remote light-gun handle with slip-on grips. You can position the handle just behind the trigger and pull the trigger with your forefinger. It looks rather like a Star Trek original series phaser. You can either cut the handle out of wood and screw on the snap that goes onto the Wii remote, or you can print the whole thing. I went for the wood+plastic solution because I didn't want to use up too much filament. This uses and bundles my Bezier library and point hull libraries. The sights are by default customized for a 2.5 meter distance to the target (the sights point slightly down so that if you align the target with the top of the sights, at 2.5 meters the target will be on the upper surface plane of Wiimote). You can adjust this customization either to have more drop or to eliminate it altogether. The sights will be useless to you when using standard Wii games and the sensor bar. For any non-decorative use they need a calibrated setup with at least four infrared LEDs around the TV and custom software that does homography calculations. The calibration stand is used for calibrating the Wii Remote with the software.
