Twisted loop

This smooth turning print-in-place loop is mathematically the same thing as my heart loop or this mini flexagon but the twisted rectangle makes for an interesting visual and tactile experience. It is especially dramatic with a color change – one of the pictures is an Amolen S-series fast change and the other is a rainbow silk (I did print 4 of them on one plate to get the maximum number of colors in it, but it's fun even with just 2 colors showing). It is a near-silent fidget. It needs supports but they are not hard to remove.
