I like to keep my ID badge for TechShop on a retractable key chain. However after pulling on it lots of times to open doors, the plastic wore down and eventually broke, falling off my keychain. Thankfully I heard it when it dropped so I didn't lose by badge but I wanted to make sure it wouldn't happen again.

Using some simple grommets, I reinforced the opening so that it shouldn't break again. In this Instructable, I'll show you how I did it!

I made this at TechShop.

Step 1: Gather Your Materials

Tools and materials needed:

Step 2: Punch the Hole

To insert the grommet, you'll need to create a larger hole in the plastic. Thankfully, the grommet set comes with the punch  that you will need.

Step 3: Install the Grommet

For the following step, I recommend doing a couple practice pieces before doing it on your actual badge. Just to see how the grommets work and to understand how hard you'll have to hit it with a hammer.

Place the grommet on top of the install base. Sandwich the plastic between it and the washer.

Using the grommet installer, hit it with a hammer. This will bend the flange of the grommet and secure it around the washer.

Step 4: Done!

Reattach your keychain and your laminate should now be much more secure. Now, I'm able to pull on it and not worry about it breaking loose at all.
<p>Great idea. I used this approach to reinforce the holes in laminated sheets for a quick medication reference chart I created. I purchased the grommets indicated in your instructable, but they were too large for my project. I found some smaller grommets at Amazon:</p><p><a href="http://www.amazon.com/gp/product/B00004Y68Y/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1" rel="nofollow">http://www.amazon.com/gp/product/B00004Y68Y/ref=oh...</a></p><p>Thanks again!</p>
