I often use a set of helping hands to grip a piece while I'm working on it but my set have always been a bit wobbly. Not anymore, with their new Sugru feet!
I love my Blackrapid camera strap but the mount has one annoying flaw. By mounting to the tripod socket it's impossible to put the camera down on a flat surface without scratching it. Easily fixed with a little Sugru left over from the above hack.
I'm a big fan of Sugru. Historically, silicone rubbers have been hard to work with and generally out of reach of makers. Sugru changes all that.
