Soccer ball puzzle

thingiverse

This is an intricate sphere made up of intricately connected hexagons and pentagons. Print the twelve pentagons in bold black ink and the twenty hexagons in crisp white, and you will see a striking resemblance to a soccer ball take shape. Make sure to include one of the pentagons with its hole and plug intact, as this unique feature is crucial to the puzzle's design. Once assembled, any external force applied will only serve to tighten the structure further. The only way to disassemble it is to carefully push out the plug, followed by a gentle nudge with a stick to coax out the pentagon on the opposite side.
