8 mm Leadscrew M3 nut holder

thingiverse

This part will hold four M3 nuts, while put on a 8 mm brass leadscrew nut, with four non-threaded holes. It helps a lot to keep the nuts in place and from spinning when tightened down. I've made and used these for my Anycubic i3 Mega S, when I replaced the brass leadscrew nuts. Unlike the original ones, the replacements didn't came with threaded holes. There is no right or wrong direction to put them one, just use them as it makes most sense to you! If you already have leadscrew nuts with threaded mounting holes, you don't need this!
