Pergola Square End Cap

We have an aluminum pergola with approx 1in square tubing across the top. Sometimes they fall out into the abyss, never to be seen again. :-) Believe it or not, I have had a tough time finding a replacement part so decided to throw together a piece myself, using TinkerCAD.

Print it out with the top on top, which requires support which easily break off. This allows the visible part to look nice.

Two STL files provided, one with a wood grain applied to visible surfaces
