Flex Fun Strip

thingiverse

Print using flexible PLA for a miniature robotic spine-like item that flexes like a finger. This design requires only assembly with a length of string post-printing. Aim for a 100% solid print and increase temperature for Ultimaker's flexible PLA filament to 230°C. After printing, thread the string through the base holes and eyelets up to the tip, securing it at the end with a knot on the knob without damaging the eyelets.
