2020 Rail sliding T nut M3

thingiverse

Needed some M3 Tnuts and man they are expensive!! I found some M3 jam nuts here, but they move around too much. So I made my own.... They don't really take a lot of torque, but if you use enough of them ... Update, newer stronger tnuts uploaded. Had trouble with cracking. Version 7 seems to work best... Also made improvements in the fit of the nut. It still holds without falling out, but does not break the slide when pressing it in. Update, made a circular array so it is easier to print. The square array had a habit of one breaking loose and knocking down all the rest. The circle prints out nice for me. Version 9 is meant to eliminate the elephant foot and make a nut that I don't have to clean. It is a bit easy to fall off, so you need a fresh bed.
