dot keycaps

mixed from https://makerworld.com/zh/models/228033#profileId-245674 Modified the keycap model to better fit the cross axisSuggest using preset angles for printing, and use matte pla material for printing to facilitate removal of supports(preset as a removable support setting for personal use, not recommended for modification)You may encounter corner shrinkage, it is recommended to slow down the speed for better cooling effect 修改了键帽模型以更适合十字轴心建议使用预设角度打印并使用哑光pla材料以便于拆除支撑（预设为个人使用的易拆除支撑设置，不建议修改） 你可能会遇到边角收缩的情况，建议减慢速度以获得更好的冷却效果
