clip-on micro Kickboard parking stopper / skid

I use my kickboard to get around on events where I help, but kickboards, because they have 3 wheels, do not need a kickstand as scooters do. They can roll away on their own and mine, because it has super smooth bearings, rolls away on its own all the time. So I created aclip on skid that I can use to block it from rolling away. It can be clipped onto the handlebar of a micro standard kickboard.
