Rear suspension bar for Tamiya Lunchbox

thingiverse

This teeny component clicks securely onto the hub where the gearbox swings freely in response to the movement of the frame. Many miniature gearboxes, like those found in Tamiya models, come with tiny metal clasps that inevitably break off soon after assembly. Once you've installed this handy gadget, your gearbox will stay locked in place, thus safeguarding the motor from striking against the suspension components and preventing any unnecessary damage.
