I modified [this design by JarnoV] to use a standard 22 mm watch strap instead of a built printed watch strap. I also made the lid a little taller to accommodate a slightly thicker cooling fan and removed the cutout for the fan wire since I ran the fan wire through the lower part of case.
Parts list:
- 5 V 40 mm fan
- 40 mm heatsink
- 12 V peltier cooler
I wired everything to a cheap USB cable and it works well powered by a USB battery pack (5V 2.1A). Powered this way it doesn't get too cold for comfort, but is pleasantly cool.
