Flexi Axolotl, dressed as Mintfin is a print-in-place flexi toy in Mintfin's colours: an ice-blue body in 6 linked segments, coral leaf gills and a fan tail, 3 black horns in the crown, and a face you can change.
Scroll, and it wiggles.
The 6 body segments are printed already linked, so the body needs no assembly. The spare face prints beside it.
Nothing inside drives it. Hold the head, rock your wrist, and the first joint behind the chest has 8° of play each way.
Each joint picks up the swing a beat after the one ahead of it: through the hips, then the first tail segment.
By the last joint the swings have added up. The fan tail sweeps about 1.0 in from side to side while the head stays in your fingers.
That small lag from joint to joint is what makes it swim instead of flap. The clearances are printed in, so it moves the day it comes off the bed.
The face is its own print. It presses onto a key under the eyes: pull the happy one off, press the sad one on.
Both faces fit the same key under the eyes, so the swap takes a second and needs no glue. Keep the other one in a pocket.
Each is printed in its own colours, with the colour changes made on the printer rather than painted on.
Body and head surfaces are Printyboy's Flexi Axolotl, carried from the designer's meshes.
