Cycling Mileage Record

为我助力第一次上传模型，希望有朋友喜欢骑行里程记录，利用齿轮-齿条配合，车轮随里程增加转动。Mileage record for cycling: By means of the gear-rack cooperation, the wheel rotates as the mileage increases.1.通过车轮随骑行里程增加转动，模拟自行车在公路上奔驰，里程记录的增加趣味性；As the wheel rotates with the increase of cycling mileage, it simulates a bicycle galloping on the road, adding fun to the mileage recording process.2.背部预留磁铁安装位置，可使用φ10mm×2mm磁铁（注意用胶粘接），磁吸在冰箱等金属表面；A magnet mounting position is reserved on the back, allowing the use of a φ10mm × 2mm magnet (note: fix it with adhesive). It can be magnetically attached to metal surfaces such as refrigerators.3.模块化设计，可以多个组件组合安装，快和小伙伴们比起来吧！With a modular design, multiple components can be combined and installed. Compete with your friends now!打印注意：第1盘底板、车架需要开启支撑；第2盘带刻度盖板需要开启薄壁检测；第3盘无特殊需求。For the first print job (base plate and frame), supports need to be enabled;For the second print job (scale cover plate), thin wall detection needs to be enabled;No special requirements for the third print job.组装注意：1.先在底板齿条上安装齿轮，先不用调整
