Celtic/Tribal Decorative Corner

A Celtic/Tribal style corner shape I made for a bookend I'm designing.

I created multiple variants including; a standard extruded piece, beveled variants, smoothed variants, bend-deform variants (suitable for creating round designs), a variant with an interlocking design similar to a Celtic knot, as well as combinations of these options, and the flat planes used to create them.

I haven't printed these separately as I'm only using them as a decorative addition, but they should all print flat without supports except perhaps the twisted options.
