Baby gate leg
thingiverse
Legs from an old baby gate vanished. 3D printer saves the day with a quick fix! Gate has square tubing on bottom so leg has exact cutout. Tubing measured 19.5mm, probably should be 20mm for perfect fit. Design made for both 19.5 and 20mm cutouts - now you can customize to your heart's content! Openscad file uploaded so you can tweak it however you like. When printed, the design looks incredibly strong. I used three solid perimeters and a 30% infill for maximum stability. A brim was added just in case, but I'm guessing it wasn't really necessary...
