Extension legs 22.5° raise - 126mm

I needed legs for a cat lair so I designed one
in general, I designed 3 different models - "normal", concave (need to use supports), concave on one side only (this is what I will be printing)

I use wood screw round 20mm length x 5mm width

rather, you can print with a layer greater than 0.2mm (i will print with 0.24mm)
