DIY Lens Cap Holder for Camera

Introduction: DIY Lens Cap Holder for Camera

This instructable shows how to make a lens cap holder for your camera.

I spent quite some time to look for my lens cap so I thought the best would be to attach it to the camera. In this way I will not lose it again. If you have your parts and materials ready (see step 1) you can finish this project within an hour.

Step 1: Materials and Components

The only special components you need for this project are some hook-and-eye closures.

A hook-and-eye closure is a very simple method of fastening garments together. It consists of a metal hook, commonly made of wire bent to the required shape, and an eye (or "eyelet") of the same material into which the hook fits. If you still do not know how it looks like go and check the picture in step 2.

Hook-and-eye closures can be found in magazines selling sewing supplies. In addition you will need some elastic and a two-component adhesive.

I recommend you to check your girlfriend's, wife's or mother's sewing toolbox first for hook-and-eye closure, elastic, needle and thread (smile).

The entire list is the following:

  1. Elastic

  2. Elastic cord

  3. Hook-and-eye closures

  4. Forceps

  5. Two-component adhesive

  6. Toothpick

  7. Post-it

  8. Sewing needle

  9. Scissors

  10. Tread

Step 2: Modify Eyelet With Forceps

From the hook-and-eye closure system we only need the eyelet. Bend the ears of the eyelet with forceps so they form a 90° angle (see picture).

Step 3: Prepare the Adhesive

For a detailed instruction on how to use the two-component adhesive check out the video under the intro.

I always have Post-it and toothpick next to me if I need to glue something (that's my job in the family). It is my favorite method because these supplies are always within a household and after the use they can be discarded.
In this project I recommend to use a two-component adhesive (5 Minute Epoxy) because it will generate a very strong bond between the lens cap and the eyelet.
Typically the two components (resins) need to be mixed together before use. This is done on the Post-it. Open up the bottles and add a drop of each component equal in size onto the Post-it. Take a toothpick and break it apart. Now mix the two components until you have a uniform solution. Since you have an adhesive that will start to harden after 5 minutes you need to speed up.

Step 4: Glue Modified Eyelet to Lens Cap

Add a small drop of the prepared adhesive to the side of the lens cap with the toothpick. Make the drop slightly larger than the modified eyelet. Then press the eyelet into to adhesive and wait until it gets dry.

Step 5: Prepare Elastic

Place the elastic around your zoom lens and cut it to the desired length. Use thread to fix both ends of the elastic onto each other. Check if the elastic fits onto the zoom lens nice and smoothly. Attach the elastic cord in the same way.

Step 6: Insert Elastic Cord Into Eyelet

Insert the cord into the ears of the eyelet. Make a knot at the end of the cord so the lens cap cannot fall off.

That's it! Please vote for me!

    Absolutely brilliant! Thank you.

    Alternatively, you could tie and knot the elastic cord around your lens and simply stick the other end to your lens cap with superglue.

    Brilliant. I'm definitely going to use this one. Thanks!

    You're welcome! Laid in bed after slipped disk surgery - so I had plenty of time to write some instructables of projects I have done in the past. Will be more difficult when I'm at work again.
