Concentric triangles pendant / brooch

Are concentric triangles a thing? I don't know but that's what I've called this pendant...

Two options:

1) Pendant - prints upside down so you need you load your top colour first. Pause the print at 1mm, change and then complete the print. This has a sturdy loop to the back for threading a necklace chain through.

2) The brooch option is more simple and can be printed the right way up. I paused the print at 2.1mm and switched colour. This one will require you to glue a brooch back on afterwards.
