Personal Peltier Cooler for 22 mm Watch Strap
thingiverse
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](https://smile.amazon.com/dp/B00NEMGCIA) - [40 mm heatsink](https://smile.amazon.com/gp/product/B07D4FVC61) - [12 V peltier cooler](https://smile.amazon.com/gp/product/B078T7J3SF) 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. Printed in black AmazonBasics PETG
