Just finished reading "Blindsight", by Peter Watts, and it was stuck in my head as I was trying to teach myself CAD. This is my first ever design so it might need a bit of tweaking. The world's most overdesigned bookmark. I guess very minor spoiler warning for "Blindsight"

Inspired by: https://www.printables.com/model/342689-tentacle-bookmark-print-in-place

Tentacle design based on: https://www.thingiverse.com/thing:2690622

Made in TinkerCAD and 3DBuilder.

Included the models for the tentacle mounts in case anyone is interested in putting these tentacles on one of their own models or on anything in particular.

Again, this is my first design, so feedback and constructive criticism are very welcome.
