Door Buddy Door Prop Extension

My friend's cat needed a little extra room to squeeze through than the Door Buddy allowed so I made a piece that connects both parts together and allows for some adjustable length.

I would print with at least 4-5 walls and supports enabled.

I used 2 M3 nuts, 2 M3x10 screws and 2 M3 washers to connect one side, and the original 2 screws on the other.
