Window Louvre Fan

Window Louvre Bathroom Extractor fan ------------------------------------------------- I lease a house that doesn't have a bathroom extractor fan, so I decided to make one! Can sit on any flat surface, but has a notch sized to fit a regular window louvre glass. Designed to hold a 120MM fan. Print standing up. I've used the fan below, it was just over $10NZD from a local IT supply store, but this should fit any regular 120mm fan. Try and find one with just two wires if possible, saves the effort trying to work out which wire is which! https://www.coolermaster.com/catalog/coolers/case-fan/sickleflow-120/ Has a cavity below the fan area for storing the excess cable. Also has a hole on the side for placing a DC terminal. I ordered a bag of the ones below. I've made the hole a bit too big, but it still works. I'll fix this if I ever do a V2. https://www.aliexpress.com/item/32834389394.html?spm=a2g0s.9042311.0.0.317f4c4diizS8a There's also an access hole at the bottom to solder in the fan wires to the DC terminal. Remember to mount the jack first, then feed the wires through the top of the print, or you'll end up doing it twice (like I did). I've included a little panel to block the access hole. It's a little too big so I trimmed it to size and super glued it in place. If I ever do a V2, I'll come up with a better solution for this. I managed to get away with 0.3mm layer height, 70mm/s print speed on an Ender 3 Pro. Is it any good? Honestly I'm not sure. If you could find a fan with better airflow, you'll see an improvement. It seems to help with moving air around the room after showers. I'll continue to use it over time and update this if needed.
