This is a print-in-place octopus with flexible legs, in the same style as McGybeer's Cute Mini Octopus. Just for fun, as a toy or fidget, or to show off the possibilities of 3D printing. Unlike the original, this one has no mouth on the side, which allows to print it entirely without supports. It also makes it slightly more realistic because real octopuses (or octopodes for the linguistic fanatics) have their mouth at the bottom. This is where the striving for realism ends though, because real octopuses obviously do not have a nose or eyebrows either.

Printing

For a strong result, use 3 perimeters. Infill doesn't matter much. No supports required at all.

A 0.2 mm layer height should work well, but 0.15 mm as shown in the photos gives a smoother result (expect between 4 to 5 hours print time at this resolution). If your slicer supports variable layer height, using thinner layers for the top of the head will provide an even nicer result (in the photos, the topmost layers are 0.1 mm).

If you can, position the seam at the back of the head to get the nicest result, especially when printing with a silky filament as in the photos. In PrusaSlicer, you can use the seam painting feature for this.

This can be scaled up at will. Scaling down could be challenging and will likely lead to a seized-up or fragile result.

Post-printing

Depending on how stringy the filament is, you may need to wiggle each joint to loosen it completely. If you place the octopus on a flat surface and rotate it by the head, it should look like the third photo if you correctly loosened the joints.
