Don't have air conditioning? Is the heat horrible? Print this to help.
Fill a couple of 500ml soda bottles with water and add 1 to 2 tablespoons of salt to each in order to lower the freezing point. Freeze overnight in the fridge.
Print a couple of these, and hang them on your desk fan or box fan. Put a towel underneath to catch condensation. Congrats, you've made yourself a DIY swamp cooler.
This print will print without supports, just snap them together. I've also included a couple of slots if you want to permanently zip tie the holder to your fan.
I hope this helps cool down your place! If its useful tips are always appreciated, lol.
