windmill gear magnet set

a education fridge magnet gear toy I create for my little one ( and her day care) every gear required one 15mmX3mm magnet I tested few other size magnets, this one is easy enough for my 3 years old to move it around, but still stay in place while turning gears it should be tight fit, and no glue needed for basic PLA let me know if you need any help with it :) Membershipjoin my membership for commercial uses
