I made this simple thing for protecting my pockets. The "butterfly" key easily tears the fabric of the pocket.

This thing fits for the total key width (from wing to wing) - 22mm; wing height - 25mm; wing thickness with the rib - 3.5mm. Tolerance - 0.15mm.

Tip: if you need the thing exactly the same size, but with the rib on another side - just mirror flip the model in the slicer.

Of course I understand that such keys come in different sizes. So, here is the source. It's so simple that I decided not to make any settings in the project. Feel free to change it.
