Maker Sebastian Dwornik needed a way to mount a mobile device to his mountain bike to field test some software he’d written. If you’ve ever tried this, you know what a pain it is to try to strap something small on to your handlebars, not to mention things can get pretty banged up while you’re out-and-about. His solution, though crude, turned out to be quite effective.

The secret comes in the form of a brilliant product called Model Magic. Originally designed for young children to express their creative talents through modeling with it. The material is safe, clean, cheap, and air-dries within 24 hours to a firm and rubbery substance that holds the shape it was molded in.

It makes for an excellent shock absorber as well as a perfect fit for any device you sculpt it for. You can even paint it any colour afterward, but I just left it stock white for simplicity.
