无需光源，无需五金，无需额外购买配件，全3D打印，即可演示昼夜交替四季变换的地球仪，非常适合用于地理启蒙教学。模型非常直观地展示了由于地球自转产生的昼夜交替。拨动右边的拨杆，表示太阳直射点的红色箭头会在0°-23.5°之间变动，符合真实的黄赤交角角度，随之左边表示黑夜的遮盖板同时产生由于太阳直射点变化造成的晨昏线的变化，直观展示南北极圈的极昼极夜现象和四季变换，正面刻度上的数字是日期，分别对应了24节气中的春分/夏至/秋分/冬至。模型附带一个海陆地球模型，你也可以自行更换经纬度地球模型或其它地球模型打印，需注意地球直径要缩放至直径50mm，南北两极开孔直径3mm。本人玩3D打印仅仅几个月，此前没有相关经验，建模设计不尽完美，但发布前也经过多次打印不断改版修改验证，创作不易，喜欢请助我一力，非常感激！为我助力创作不易，喜欢请助我一力，非常感激！附简单的安装技巧，让你安装更顺畅：
