Smart Watch

do not mix the water with the watch. you have been warned.

Prefer WearOS watches like LG W100. Found 3D printable case on Shapeways but not downloadable. Shapeways provides service for printing. Shapeways builds ShapeJS which can construct 3D models with code.

Use Pixle2Mesh++ to recover 3D meshes from multiple images (dumped at ~/Desktop/works/shapeways_reconstruct_from_image_lg_w100)of different viewpoints. Determine the size of the mesh after measurement or learning specs.

if you want iwatch instead, remember to buy some apple gift cards for buying watchos apps. remember to ask for battery life since older watches tend to die halfway in a day. buy iphone 6s and newer models with ios 14 and newer os to manage and install apps on iwatch. no need for 3d modeling since plenty tough-tested cases around.

智能手表防水 泡温泉 外壳

智能手表都不能泡温泉 洗澡

可以考虑做智能手表的时候添加耐温耐水蒸汽的胶水 也可以考虑做防水汽的外壳 塑料透明保护壳 胶圈要和塑料壳之间用耐温耐水汽的胶水粘连 胶圈之间添加波纹 纹路 增加密封强度 耐压 用铰链链接 卡扣扣住 或者双卡扣

如果外壳需要留空间给按钮 用橡胶按钮加耐压防水胶 或者粘贴实体按钮 硬质按钮加橡胶密封层 注意连接处面积要大

旋转的按钮就不要旋转了 因为无法密封 比如苹果iwatch 只能点按

外壳一般有配套的表带 不用原来的连接装置
