Retract-A-Gate Bracket Replacements

I have several retract-a-gate(s) and needed replacement brackets. I designed these in TinkerCad and they have worked perfectly. I also made a version that stands 20mm additional off of its mounting surface to accommodate the difference in height caused by baseboards. These brackets are a bit thicker than the originals as I wished them to be a bit stronger.

I've got a pair of curious puppies dashing about the house right now. I made an additional style of bracket that retains the gate, but more loosely than the standard design does. I use one of the "looser" style in locations where that bracket is in a poorly accessible position. For instance, when using three brackets at the base of a stairway, the upper two brackets are the standard design, and the bottom bracket the "looser" style. That (so far) prevents an incorrigible, intrepid, investigating puppy from worming their way through any gaps.

Update: Unfortunately, none of this prevents a certain puppy from going OVER
