Simple Door Latch.

thingiverse

Originally designed using Moi3d software, this model features clear PLA material and was sliced with MakerWare Slicer at high settings as default. It's a simple solution to an old screen door problem - it replaced a latchless door that wouldn't stay shut. Plus, it's designed in inches, so just remember to scale up when opening the file in MakerWare for accurate printing!
