TS457内阻仪测试支架，现有的版本要么不带测试座，要么尺寸巨大，所以只能自己画一个了，测试探头部分可伸缩，兼容18650及21700，滑动探头为tb购买的18650测试架探针，滑动部分使用8颗4mm直径*1.5mm高磁铁定位，整机使用12颗M3*14沉头内六角螺丝装配，内置一节18650，以及一块超小三元锂电池充电板给内置电池充电，目前没有预留外接探针的插口

我使用哑光pla打印的，理论上使用petg或pla打印均可，安装完成后滑轨部分可能会卡顿，多滑动滑动就好了

由于着急使用，做的比较粗糙，如有其他需求请留言，谢谢

The TS457 internal resistance tester test stand is either not equipped with a test stand or has a huge size, so only one can be drawn by oneself. The test probe part is extendable and compatible with 18650 and 21700. The sliding probe is the 18650 test stand probe purchased by TB, and the sliding part is positioned with 8 4mm diameter * 1.5mm high magnets. The whole machine is assembled with 12 M3 * 14 countersunk hex screws, with a built-in 18650 section and an ultra small ternary lithium battery charging board to charge the built-in battery. Currently, there is no reserved socket for external probes
I used matte pla printing, theoretically both petg and pla printing can be used. After installation, the sliding rail part may get stuck, just slide more and it will be fine
Due to urgent use, it was done relatively roughly. If you have any other requirements, please leave a message. Thank you
