Vernier calipers游标卡尺

网上看到不少卡尺作品，都不太好精度也不够，那我就做一个精致的卡尺吧，精度0.2，量程150mm，凸纹数字更精致，带手导轮控制精度更方便，带深度尺，安装好后有行程限位，不易掉出，注意深度尺槽位置不用加支撑，组装视频放在打印实拍。

Online to see a lot of caliper works, are not very good accuracy is not enough, then I will do a delicate caliper, accuracy 0.2, measuring range 150mm, more refined figure, with a hand guide wheel control accuracy is more convenient, with the depth of the ruler, installed after the travel limit, not easy to fall out, pay attention to the depth of the groove position without support, assembly video on the print real shooting
