胸带支架方便，比头盔支架轻，比双肩包支架稳。

灵感来源于Insta360官方自行车支架，修改为卡扣快拆式，适用于日常通勤，骑行记录，如果有违章乱骑的电动车，这个也可以作为更有效的记录.

理论上适用于Insta360 X2、X3、X4，具体可以自己试一下。我是用Magics进行修改的，如果尺寸不对可以联系我修改。

可以先将模型对半切开，打印一半进行测试一下，如果安装无问题再进行打印。

建议使用PETG材质、4-5层壁厚，填充100，树状支撑。

The chest strap bracket is convenient, lighter than the helmet bracket, and more stable than the backpack bracket.

Inspired by the official Insta360 bicycle bracket, it is modified to a snap-on quick-release type, suitable for daily commuting and riding records. If there are electric bikes that violate traffic rules, this can also be used as a more effective record.

In theory, it is suitable for Insta360 X2, X3, and X4. You can try it yourself. I used Magics to modify it. If the size is wrong, you can contact me to modify it.

You can cut the model in half first, print half to test it, and then print it if there is no problem with the installation.

It is recommended to use PETG material, 4-5 layers of wall thickness, 100 filling, and tree support.
