My Window Vent Latch broke and I had trouble finding the exact one to fit. Instead of spending time buying and returning them until something fit. I printed these!

I added some extra material where the window makes contact with the latch to prevent breaking in the future. I also printed it out of solid ABS, 100% infill and printed on its side.

I used an ender 3 and creality abs filament.Took about 23 minutes to print with a raft and supports

This design might not fit every application but it's easy enough to modify the part to fit your application. I added a picture of the original window latches, so you can compare yours and decide if these will fit.

I've had it for a couple weeks now and It is holding strong, works great!
