STEP 1a: Press-fit 5x Small pins into the holes of a Pentagon Block
STEP 1b: Press-fit 5x Hexagon Blocks to all 5x sides of the Pentagon block above. Use small pins to interlock all blocks together
STEP 1c: Press-fit 5x Pentagon Blocks to the sub-assembly from STEP 1b. Use small pins to interlock all blocks together
STEP 1d: Press-fit 5x Hexagon Blocks to the sub-assembly from STEP 1c. Use small pins to interlock all blocks together
At this point, you’ve built half of the soccer ball. Repeat the same steps as above to build the other half. To connect 2x halves of the sphere together, you can either use the small pins, or some 5mm dia x 3mm thick magnets.
