This is an end cap for 3/4″ by 3/4″ angle aluminum stock. It can be used as a foot or to finish off the top for appearance and safety. The fit is rather tight so I would suggest printing one and try in it as the gap is around 0.06″ with a bit of overlap on each side. These where printed in ABS with thick shells and 30% in fill.
