The 'Rotating Golf Ball Key Fob' is approx. the same diameter as a regular golf ball but slim (only 5mm thick) so it fits easily onto your key ring... not a 'ball in your pocket.
The ball features dimples of a similar size as a regular golf ball and the centre (ball) section is independent of the outer ring so it rotates freely. This is a simple one piece print comprised of two parts that rotate around each other.
i recommend printing at the current scale to maintain the clearances designed in (so it rotates freely) and make the ball a close representation of a dimpled golf ball size wise.
After printing remove the raft (if used) then gently wiggle to free inner part until it starts rotating freely. With most good (accurate) machines the centre should free quickly and easily making it a spinning ball inside the slimline outer ring.
The file is quite large due to the detail in the dimples on the ball surface... but well worth the download. If you're a golfer you will appreciate this, if not. but you know a golfer, print one as a gift.
