These "chair clamps" sit at the corners of a rectangular wooden chair when clamping it with a sturdy nylon strap.

My wooden kitchen chairs were starting to get wobbly at the joints after 20+ years of use, so I put some wood glue in the joints and clamped them to dry overnight. The clamps keep the chair finish from getting damaged from the straps. There's also a "diagonal" for clamping corner supports (see pics).

Print 4x corners, and a diagonal or two, depending on your needs.

To make them sturdy for the clamping forces, try setting 5 perimieters with 20% infill. This worked well for my setup, when using PETG. The PETG is glossy enough to let the nylon strap slide over it when clamping.

Tip: see the picture of the whole chair, and the clamp that is twisting the strap for more tension on the clamp. This really made things snug!
