Window Track Locks for Home Windows

The windows of my house have these track locks on the sides that when released allow my window to fold into the house for easy cleaning. Problem is that they are plastic and break easily. The only way to get replacement ones is to have a windows installer company come out, the manufacturer won't sell them to the public. So the very first thing I created with my Da Vinci 2.0 Duo 3D printer was replacement Track Locks.
