Aggiunta nuova cerniera per blocca cancello in modo che si possa apre sia in avanti che indietro

My dog is very attached to us and really feels our absence. My goal was to make the few hours she spends alone a bit easier by building this dispenser. In the end, it turned into a game she absolutely loves, and I plan to create different versions of it. If you have any suggestions, feel free to share them!
