Replacement Window Latch

The window latches for my house broke and I was told that those latch types were no longer made and I needed to purchase a whole new window. Since I have 20 of these windows it's only a matter of time before they all start breaking. So I came up with this model and they ended up working real well. 

I ended up picking up the spring in an assortment from Amazon - https://a.co/d/fSTbaNT

Now when one breaks, I just print a new one.
