Office Essential: “Use Your Brain” Brain Core Wrist Ball

Design concept: Centered on "office wellness + creative stress relief", this ergonomic fitness ball combines a "brain shape" with "walnut fidgeting" to create a product suitable for office environments. It not only inspires work through its fun shape but also, with its lightweight single ball (14g+) and palm-fitting design, allows users to exercise their wrists anytime during breaks, thinking, or meeting intervals, alleviating wrist strain caused by prolonged sitting. Suggestion: single ball diameter = (your shoe size + 1) mm

Many support methods were tried, and settings have been finalized, it is recommended not to modify them

After removing supports, you can trim the bottom of the model and use a heat gun to achieve a relatively perfect bottom (the left side is untreated, the right side is processed)

You can explore various materials, especially printing a pair in PLA Basic Gradient colors simultaneously to get unique and consistent patterns

PETG Translucent and PLA Silk also perform very well
