I recently got a new chain for a buddy's motorcycle, and it came with this free tool. I decided to design a custom tray to fit it nicely into my toolbox. If you're interested, you can find the tool on Amazon (HILAKE #428 520 525 530).
To keep things secure and prevent rattling, I added magnets. For the smallest magnets, I used the punch from the tool itself—just attached a small magnet to the end, placed it over the hole, and gave it a couple of light taps with a small hammer to set it in place. The other magnets are simply press-fit.
For a finishing touch, I poured some Flex Seal liquid into the tray. It not only helps lock the magnets in place but also gives the tray a cleanish less DIY look.
