Simple Manual Sleeve

可以辅助拆卸螺丝，做了3款，等效10mm、13mm、16mm螺丝及六角螺母，采用贯通设计，避免了一些螺丝过长套筒无法使用的尴尬情况，我采用的是拓竹pla，辅助拆螺丝够用了，如果换petg或abs应该会更好，注意，太过紧固的螺丝螺母，最好把松一下再使用套筒辅助拆卸，毕竟无法等同于金属，只能做辅助使用。 I have made three models that can assist in disassembling screws, equivalent to 10mm, 13mm, 16mm screws and hex nuts. They adopt a through design to avoid the embarrassing situation of some screws being too long and sleeves being unusable. I use Tuozhu PLA, which is sufficient for assisting in disassembling screws. If you replace it with PETG or ABS, it should be better. Note that for screws and nuts that are too tight, it is best to loosen them before using sleeves to assist in disassembling, as they cannot be equivalent to metal and can only be used for auxiliary purposes.
