Door Ajar-er

My puppy kept locking herself in rooms by pushing doors closed and not being able to use the handles. So I threw something simple together in TinkerCAD. It slots over the door at the corner and meets at the frame.
It is shockingly resilient as I tested a few door slams and it survived.
It might be ideal to add felt or foam or something to the end where it hits the door frame. I did not do this yet, however, to prevent damage to the door frame. Might be a good idea.

If anyone wants the file, let me know, or if you need me to change angles or openings. Please let me know as well.
