Oh, lenscap, wherefore art thou? Seriously, where the heck did you go.

Like socks in the wash, we’ve misplaced more lenscaps than we care to admit.

That’s why Swedish inventor Benny Johansson developed the SkottiRotta, a DIY lenscap-keeper that cozies up to your camera strap.

Now you can put the kibosh on dust and scratches — not to mention on buying a new cap almost as often as you have to buy new socks.

Making a SkottiRotta couldn’t be simpler: a little plastic, a little paper, a cord and some hole-punching, and you’re done!

What You’ll Need

  • A pushpin
  • An x-acto knife
  • Scissors
  • An electric drill
  • A plastic container (recommended: the type with a “2” in a recycling triangle)
  • Elastic cord (aka “shock cord,” 2.5 mm diameter and 25 cm long)

Step 1: Cutting Things Out

Download the SkottiRotta template and cut out whichever shape fits your camera strap.

Next, cut out a rectangle of plastic large enough to cover the template shape. Tape them together so you’ll know where to cut.

Step 2: Closer Cutting

Make perforations along the edge of the shape with a pushpin. This will make it easier to cut it out.

Use a drill (or, if you like, a hole puncher) to cut out “eyes” for the strap and the cord. Err on the side of “too small” to start with — you can always make the holes bigger.

Step 3: Trimming the Excess

Take off the paper template. Use scissors or a knife to trim away the excess plastic, using the pushpin perforations as a guide.

When cutting out the “mouth” that will hold the cord, make it too narrow to start. If you make it too wide, then it won’t hold the cord — but if you make it too narrow, then you can always narrow it in small increments later, ensuring a perfect snug fit.

Step 4: Lenscap Drilling

Now for some fun with power tools!

Use a drill to (carefully!) make two holes in your lenscap, the same diameter as your cord and 12mm apart. Make sure that you place the holes at a point in the cap where there’s enough room to thread through the cord and make a knot.

Step 5: Secure the Cord

Next, thread the cord through both holes and tie them together with a simple “tying my shoelace” knot. Then give them another knot to keep ’em tight.

Now just snip off the excess cord and ta da! Nearly done!

Step 6: Put it all together

You’re in the home stretch now: slip the strap off of your camera and thread it through the slits that you made in the plastic. And now whenever you remove your lenscap, just squeeze its loop of cable into a SkottiRotta notch. Life simply cannot get any more worry-free!
