The Bianchi Specialties Dongle Hanger is designed to fit the dongle of a DiFalco Genesis slotcar controller. 

The Dongle Hanger is used to support the dongle, taking its weight off the controller handle, the plug or the alligator clips.  It has a hook which allows you to hang the dongle over the retaining wall of a slot track, or any other such surface, 1/2 inch thick or less.

The Dongle Hanger is 3D printed in flexible polyurethane, which allows it to snap into place over the standoffs of the dongle.  It can be fit with the length of the dongle either vertical or horizontal, as shown.

Check the dimensions of your controller dongle to make sure the Dongle Hanger will fit.  See the sketch above.  The screws and stand-offs must be on the centerlines shown, and the gap between the circuit board and the heat sink must not be less than 0.346 inches.

Color may vary.
