Double sliding closet door. My basement closet door doesn't have the bottom track. These keep animals and small kids from pushing into the closet with the doors closed. Requires Sliding door catch to be printed twice. one for each wall the door touches. I didn't design holes these because it was faster to drill two holes into each part. The Sliding door catch v1.3 one print one snaps to the center of each door allowing them to interlock when slid closed.
