Built from separate parts that can be swapped, such as plates, shells, buttons or cores.
What it is
A modular fidget is designed so that main parts can be exchanged. A slider might take different plates or shells, a spinner different buttons, a coin different faces. Parts are only interchangeable within the system the maker designed.
Why it matters
Modularity lets one body change its look, weight or feel without buying a whole new piece. Always check compatibility by model and version; parts that look similar may not fit.

是什么
模块化玩具在设计上允许更换主要部件：推牌可换板片或外壳，陀螺可换按钮，响币可换面盖。零件只在品牌设计的同一体系内通用。
为什么重要
模块化让同一个主体换外观、换重量、换手感，不必整件重买。更换前要按型号和版本确认兼容，看起来相似的零件不一定装得上。
又称：Modular Design、Swappable、Interchangeable、可替换、可换件。
