I improved this model so you can print it without supports all over the place. You only need a line down the middle, as I show in the 3mf file, for the ones without holes, or a small amount around the connectors for the ones with holes.
200, 250, 300, and 350mm versions provided.
Currently experimenting with different materials to get the right amount of “flex” - TPU or PETG so far seem the best.
