Double Hung Window Latch

First creation - just got first ever 3D printer and was almost immediately asked if I could make replacement window latches for my sister-in-law. Looked for some here, but none matched theirs, so I grabbed my calipers and learned how to use Sketchup. They said these worked perfectly, no tweaks required. Not sure what their window manufacturer is, but a member commented that it was for Wallside/Hanson/generic-style vinyl double-hung windows.
