Yale Doorman V2 child proofing

prusaprinters

My two year old just figured out how to unlock yale doorman by turning the thumb turn. To prevent this I made this simple thumb turn lock, which just slides onto the handle and then pushed onto the thumb turn. I also added velcro on the backside, but have not had the need to use it yet.This may work for a couple of months until he figures out how to pull the whole thing off.
