18650/21700圆柱锂电池充电夹座
Source: MakerWorld by en~
The 18650/21700圆柱锂电池充电夹座 is a free printable 3D model from MakerWorld by en~. 做这个是为了方便给手里的3种规格电池充电，18650、21700和17670，桌子已经很乱了，不想每个电池都配一个充电器。 打印前请先校准好材料收缩，避免出现安装公差的问题，如果校准后还是出现安装公差问题，文件内有上传原始文件，可以按照自己的耗材或手头现有的材料做修改 需要的材料：C口TP4056带保护充电小板 1个 电池极片 1对弹簧. You can download the STL file from the original listing below and print it at home.
About this model
做这个是为了方便给手里的3种规格电池充电，18650、21700和17670，桌子已经很乱了，不想每个电池都配一个充电器。 打印前请先校准好材料收缩，避免出现安装公差的问题，如果校准后还是出现安装公差问题，文件内有上传原始文件，可以按照自己的耗材或手头现有的材料做修改 需要的材料：C口TP4056带保护充电小板 1个 电池极片 1对弹簧 1个，弹簧尺寸：长35-40mm，外径20mm，线径1.0-1.2mm（线径越粗越吃劲，建议用不锈钢的，我手里是有现成的1.0和1.2mm不锈钢丝，自己绕的，文件里有绕制用的简易模具，模具需要一颗M416的内六角杯头机牙螺丝）导线：正极长约125mm，负极约60mm螺丝：M25盘头平尾自攻螺丝 10颗 下面安装：先插入极片放入弹簧，用手压到底斜着将负极滑块的一端放进滑槽，顺势斜着按进去，直到将另一端按进滑槽，来回滑动测试一下顺滑度，看滑槽是否需要进一步打磨切削测试，练习装配（如果觉得导线长度不合适，这一步装好后可以测量需要的导线长度），按图放入负极滑块底脚，再旋转放正，觉得麻烦可以剪掉滑块底脚（剪掉后缺少一个限位，滑动的稳定性可能会差一些）测试好后需要取下来安装充电模块，充电模块先焊好导线，再放入槽内按到底，充电插口位置可能需要用工具辅助调整一下再按安装的时候注意先把线穿过来，然后重复前面测试的步骤拧上4颗M2*5的螺丝，图是画的6个孔，实际安装用下来，装4颗就可以了螺丝装好后按图把极片的脚折过来，并上好锡焊好导线，再打两个圈（负极的圈是推拉滑块时免得线乱跑，正极的圈是留长了），这里插电测试一下最后装上底盖，剪一截透明耗材，大概3mm长，放入小孔按平（不要也行，就是传导充电灯光的，不影响使用）
