If you have a camera with a lens, you know the length you need to go to ensure that you do not lose the cap. My solution is usually to get it stuck in my back pocket, but I 'm always afraid I'll break the cork in this manner. I do not want a lens that cost between $ 20 to $ 40 to replace. Instead, you can create a lens cap that guards for no cost.

The steps are very simple, plastic insert from a bottle of shampoo or something to that effect. Then you print the pattern and tape to your flat piece of plastic. The rest is pretty easy, and fortunately none of the tools you need are out of the ordinary. The only one to give people problems is a bore, but you can replace this with a drill. It is a complete tutorial and printable templates that you can check.
