Safety Gate Additional Lock

I call this the Mikey lock, after my cousin's son (he's not yet 2yrs) decided he could work out how to open the safety gate and get into the kitchen for a snack. 🤦😂

The tolerances and clearances are quite tight (so even if he learns, wont have the strength to open). 

was printed on K2 plus  (0.4mm Nozzle) 0.2 Layer height printed in PLA 5 walls 15% infill with supports (I used tree).

It print in place if you orient it on the side.
