Turns out rubberband "rainbow loom"s are totally a thing now. I wanted an easier way to make circular chains like the "fishtail" and "hexafish" so I created this 3d printable mini-loom.
You can control the number of pins, spacing and other things, but you'll need to play around with the variables to get something usable (the defaults are fine though)
