Child Proof Door Handle for keypad locks. I forgot to add a hole for the keyway so I improvised when installing it. I have added the Solidworks model so you can add the hole yourself.
To open the handle you have to push the lever upwards to open. You are still able to open from the outside normally. Please don't push it downward from inside the home or you'll break the print.
The author marked this model as their own original creation.
