I tried using sugru to make my favorite mechanical pencil more comfortable. Mom stole some sugru for a project of her own. The leftover sugru became Sugru Man. He slides around on my desk.
Sugru was fun and easy to work with, but it doesn't seem very durable. It peeled off my pencil within a few uses. Mom used it to make replacement buttons for a fan switch. They broke off within a few days. Maybe it doesn't stick as well to plastic? Sugru Man alone has survived. He has been dropped off the desk, run over by a chair, stepped on, nearly vacuumed up several times..but he prevails.
