da towster vehicle side unfaired

Addition based on suggestion from the forum:

 Vehicle side of the coupling for vertical dropouts with the typical 9.8mm flattened quick release axle and solid axle with nut, such as those found on hub motors. This means that the towster can also be used with unfaired bicycles.
 The part goes on the left side of the rear wheel from the outside onto the dropout and is attached with the usual quick release or wheel nut. Please ensure that it is 3mm thick and that the quick release axle or wheel nut still has enough thread.
