M3 Spacer Clip M3垫片夹

1.8 mm thick removable M3 spacer that can be clipped onto a M3 machine screw. I designed this removable spacer because the spacer rod we got wasn't long enough, and moving bolts and nuts is too much work because everything is upside down. 1.8 mm厚M3垫片夹。之前项目组买的M3塑料柱不够长，且由于拆除螺母螺丝太过复杂（所有东西都是挂在机器顶部），就搞这个玩意儿。
