I always seem to lose the caps to my USB thumb drives.  I figured I could use some Sugru to make a new cap.

I didn't want to risk gumming up a USB drive, so I decided to use a USB cable for the mold.

Step 1: Make Sure the Cap Will Release the Sugru

I didn't want to put a releasing agent on the USB cable unless I had to, but I also didn't want the Sugru to bond to the USB cable. I decided to cut a small part of the Sugru wrapper to use around the USB cable.

In the photo, the  wrapper looks pretty loose, but I was able to get it tightly wrapped around the end of the cable and secured with a small piece of tape.

Step 2: Sugru It!

I molded the Sugru all around the end of the USB cable until I was happy with the shape.  When I was done, I trimmed off a bit of Sugru near the open end of the cap.

Step 3: Let the Sugru Setup

I let the Sugru setup for about an hour before pulling it off the cable.  It released with no problem.
Sugru is like silicone but you get way less for much much more money
I've never heard of Sugru. But I need to make a few iPhone 5 lightning cord caps and this will work great. I need caps for myself, and I can make some for other people too. I could shape the Sugru so I can put a string through it to attach to the cord. <br> <br>Thanks.
I love Sugru. But considering that it costs $15, it would be easier and cheaper to just order a USB replacement cap. There are a few companies selling them for just a couple of bucks! Try RooKaps.com or L-com.
Pretty average DIY. Lack of detail and images. Doesn't really show anything. Sorry, but honesty is what you need.
