How to Make a Lens Cap Replacement for Your Camera Lens

Preparing the Foamcore

Start scoring one side of the foamcore the short one inch (2.5cm) way. Do this the whole length of the foamcore strip. Take a strip of tape as long as the foamcore length. Apply it to the unscored side of it. This will reinforce it and keep it from tearing.Make a Lens Cap Replacement for Your Camera Lens Step 2Bullet1.jpg

Trace a circle around the circumference of your lens on the foamcore.

Cut it out. You can use your cutting tool that you will use later, or scissors.

Creating the Lens Cap

Apply the tape that you are using. Stick it to the inside of the circle that you cut out earlier.

Stick a piece of tape across the other side of the circle that you just taped. You want it to stick out on either side of the circle about an inch and a half (2.5-3cm) or so. Start attaching the already taped scored piece of foamcore, as shown in the image, gently curving it around to fit on the circle piece.

Cut the piece of tape that is still jutting out along its center. Cut right to where it joins the foamcore. Doing this allows you to eliminate any bumps in your taping that may otherwise be caused from taping the circle.

Continue doing this all the way around. Periodically, put it on the lens to make sure that it is holding its shape. You want to make sure that it will fit snugly on the lens and, yet, not be too snug.
