Locking Latch with Teeth (Key included

thingiverse

This is a latch with teeth that can be imported into any design and used to secure one surface to another. The Latch needs the included key to un-latch. This can come in handy when you don't want the latch tampered with... or at least make it difficult to tamper with. It can be scaled uniformly based on the size latch you need. Print the Key horizontally for strength.
