Foot for an L shaped Kickstand

My wife has a Trek Belleville that she loves. The kickstand has always been an problem as it is just a little bit too short. I found putting a small spacer under it stopped the bike from falling over. Of course it has a bend at the bottom so normal kickstand feet do not work. Printed in TPU. Does not need supports the inside is domed. So far I have not need to add adhesive to the foot to keep it in place
