Summary

A simple door lock to keep the kids out of the closet. Easy to modify SLDPRT file for different thickness doors. Prevents the door from opening when in the center section, slide it over to open. Simple and effective!

Instructions

In a Makerbot or anything similar print the file with the added ledge flat side down with supports. There will be a little .4mm support added on top of the long square bricks you can then break off the handle.
Makerware fails to make support on this geometry. I have not tested ReplicatorG

On a Stratasys machine, just print the simple file flat side down.

I made the part 1" Longer and 1" Larger so it does not pop off on certain doors. You will still need to modify this for your particular size door.
