Personal Peltier Cooler

thingiverse

This personal cooling unit will make your summers a little less sweltering. Attach it to your wrist for optimal blood circulation. Best used in my opinion between 5 volts to 8 volts. You could use up to 12 volts, but be cautious - it doesn't get too chilly (or too scorching on the other side of the Peltier module). I used 100% infill. No rafts or support were needed. 3D printed parts used: -cooler with band.stl -cooler lid.stl -band extender.stl (optional) Electronic parts: -40mm Peltier module (12v) -10x40x40mm heatsink -10x40x40mm fan (12v) -Thermal paste between heatsink and Peltier module (optional) Assembly: 1. Slide the Peltier module (cold side down) into the bottom of the cooler, there is a raised lip where the module should fit precisely. If it doesn't, use some glue. 2. Insert the heatsink from the top into the cooler, put some thermal paste in between them if you have some. 3. Insert the fan from the top into the cooler, make sure that the wires are facing upwards. 4. Clamp on the cooler lid onto the cooler. There's a small hole in the lid designed for the wires of the fan to exit the enclosure. 5. (Optional) If you're using the cooler with band, you'll probably need at least one extender. Just attach it to the rest of the wristband. I edited the 'Pebble Watch Strap' design from GuyChernobrov for the strap/band: https://www.thingiverse.com/thing:1652742 Enjoy! But don't expect any major cooling - it's just one small and underpowered Peltier module.
