Introduction: Reinforcing Cables With Sugru

Sugru is a self-setting rubber for fixing, modifying and improving stuff.  It molds like play-dough, bonds to almost anything and turns into a strong, flexible silicone rubber overnight.  It comes in several colors, and is great for all sorts of things.

Computer cables have a nasty tendency to wear out, right at the joint to a firm piece.  Why?  Because the cable bends back and forth against that firm part.  Let's reinforce the end of the cable a bit so that it doesn't bend quite so sharply.

Sugru in the desired colors (You can mix colors if you like!)
Computer cables (power, mouse, etc)  You can upgrade up to 5 cables with one small packet of Sugru!

Step 1: Open the Sugru

The Sugru comes in little metallic packets to help keep it fresh.  There's dotted lines on each packet showing where to cut the packet open.  Go ahead and cut open these three sides, peel the packet open, and scrape the sugru out.

Step 2: Knead and Mix the Sugru

Knead it up for about 30 seconds to get it activated.  This is a good time to mix up different colors!  Your working time with Sugru is only about 30 minutes, so don't take too long.

Step 3: Divide Up the Sugru

A little goes a long way with this project.  For each packet of Sugru in your mix, divide it up into 5 equally-sized pieces.  If you've mixed two packets of Sugru to make a new color, divide it up into 10 pieces!

Step 4: Shape the Sugru

To make it easier for forming around the power cable, shape the Sugru into a little "nugget" or short worm.

Step 5: Form the Sugru and Let It Cure

Mold the Sugru nugget around the end of the power cable.  Make it thicker at the end close to the hard pieces, and thinner the further away it goes from there.  This lets the cable bend gradually instead of sharply, helping to prevent breaks.  Then, make 4 more!

Wait 12 hours, and it's ready to go!
