2025-11-28 Update: Added an alternative version brought to my attention by @Fishy_3930160 Outer dimensions are 8 x 8 inches.
The original was blocking the entrance to an attic vent in my 1800s era house. The design itself is probably from the 1920-1930s. It's really beautiful so I modeled it to make more of them. I really like the design not just because of its aesthetics but it is highly functional too, it keeps my two troublesome cats out of the walls lol (although they do stick their paws through sometimes).
There are two countersunk screw holes in the sides for fastening. The first picture is of the original metal object, not that I doubt anyone will be fooled, but I wanted to include it so you can see what a close copy it is.
For printing I scaled it down to 120 x 117 x 2.6mm.
The author marked this model as their own original creation.
