Stop searching your pockets for lens caps by making this handy DIY
Keep your lens cap's from getting lost all over the shop with this clever Lego and Sugru hack.

And if you don't have Sugru you could always use Araldite for extra strength and resilience to tough camera abuse. I did both and I've got to say I'd trust the Araldite a lot more.

    Step 1

    Gather your materials!

    It's probably best to use the flatter pieces of lego (1/3 the size of the regular pieces) as you don't want the Lego to catch on things.

    Use whatever colours you like and you don't have to use a colour of Sugru similar to your Lego, it just helps to give the Lens Cap saver a modern and proffessional look whilst also being functional.

    And if you're using Araldite or some other form of glue instead of Sugru then follow the instructions according to the packet but follow a similar method as this tutorial.

  • Step 2

    Spread a blob of Sugru on to your lens cap about the rough size of your Lego piece with the bricks bump face upwards (make sure you don't put it in the way of the clasping mechanism).

    Fill the underside of the flat Lego piece with Sugru and then push it brick side up on to the lens cap Sugru mound, pressing the two pieces together but be careful not to apply too much force as the Lego pieces could cut through the Sugru rather than adhere to it.

  • Step 3

    Smear a tiny piece of your Sugru on to your fabric camera strap and build up layer upon layer to give the Sugru strength against the flexible material, then push the Lego flat face side down in to the Sugru mound until it adheres.

    Sugru is only pliable for thirty minutes after the packet has been opened so you should work fast and find a side project to use the rest of your Sugru on after you've finished this project. Sugru needs 24 hours to dry fully and to form the all important bond we need to keep the Lego securely in place.

    Of course you could use your spare Sugru on turning everything and anything in to a lens cap port; your camera bag strap, a belt, a boot, whatever you use to go snapping your pictures you can paste Sugru on it and make it a Lens Cap safehouse. Also you could put Lego Flat's on each of your Len's caps.

    Once your Sugru is dry you're good to go. You can also do this tutorial by replacing the Sugru with Araldite for extra strength and use whatever Lego pieces you like to snaz it up a bit.

This is the best idea ever! I'm always losing my lens caps because they don't have strings on. Time to get the sugru out...
