Two possible explanations.

In-series, possibly it can change its shape to match the user. (Don't add this to the page until we can get a verdict, please)

Real life, they were shooting a combat scene, so the prop Gai uses simply wouldn't cut it, and the one we see Orb Origin using is just too big and bulky to be a good match for Juggler's fighting style.
