Traxxas TRX-4 Remote Undercarriage Power Switch

There is no modification to the mount. The design of that part is flawless, and works flawlessly. Several adjustments have been made to the rocker design: 1) The rocker has been lengthened and rounded off so it can be actuated without a tool. I know there are mixed opinions on this, but see the video - it's not protruding in an area where I can imagine anything other than a stick pointing straight out of the trail catching on, and its reverse motion is limited by change #2. 2) A dimple and slope have been added to the ESC side of the top portion of the rocker so that it cannot swing in the reverse direction more than ~1mm. This further reduces any possibility of the rocker getting down into a position where it could interfere with undercarriage clearance. 3) The thickness of the rocker has been adjusted where it goes through the mount (made slightly thicker) to reduce side-to-side motion. If it's snug after you print it, make sure you've trimmed off any jaggies at the edges that may have resulted from overhangs or supports. 4) The thickness of the rocker has been adjusted where it goes between the body and slider (made slightly thinner) for better clearance. On some trucks (like mine) the original was too tight here, as the sliders sat just slightly closer to the body.
