Double Door Lock

thingiverse

I modeled a locking mechanism for my double doors to keep a pet out of a room that they had learned to get into. The design was made with my doors in mind, and my pet in mind, and may not work perfectly in your application. As an example, lock does not fit 100% perfectly on the interior of the exact same door it was designed for. Currently it is 5mm thick. This is what I would consider to be minimum viable. You could probably stand to increase it to 6mm or maybe even 7mm. 10mm+ would be ideal, but for my doors, would require some resizing as the lock would make contact at different locations due to the increased size. Also bear in mind that if you increase the thickness, the flexibility of the arms will reduce, requiring you to be more precise with your measurements/printing.
