齿轮启蒙-万花尺（超大号）

来自中国80-90年代的记忆。一种插入笔后随着齿轮的转动，能画出“万种”花纹的尺子。曾经是儿童时对齿轮运动的启蒙。现在做一个超大版。来自随机性的设计，最大单个可以做出直径190MM的花纹艺术（齿轮轨迹）A memory from China's 1980s and 1990s. This is a special ruler that creates countless intricate patterns as gears rotate when a pen is inserted. It once served as kids' first introduction to gear movement. Now we have created an oversized version. Featuring random design effects, the maximum diameter of a single gear track pattern can reach 190mm.
