The Beta Ball
Challenging
Attach the grips in new positions as you see fit.
Easily increase or decrease the level of difficulty.
Customizable
Use the grips provided, print your own, or attach whatever you think would make a great grip!
Universal Hardware
The Beta Ball uses M5 Hex Bolts.
That means you can easily get yourself more or longer bolts, or replace the allen key should you lose that tiny bugger!
PS: The allen key is the same size as IKEA's basic one. You definitely can't get yourself a spare one, or fifty, at this page. 😉
Colorful
The Beta Ball is almost fully 3D printed, except for the nuts and bolts, allowing for infinite possibilities in personalization of color, style, and difficulty.
