Summary

I wanted to use a lead-screw so had to create a new nut-lock for the lead-screw nut.

I've used a TR8x1,5 leadscrew and corresponding nut for it.

Blue and Black part
The blue prints here are the non-reinforced while the black prints are with a bit thicker walls.
Nut sits a bit higher in black part (0,3mm)

If the nut is not flush with the edges of the print you need to either sink it in some, or print a tiny spacer to make it flush.

Post-Printing

Cleanup

            <div><p>You might need to cleanup that guide-tap at the top of the print.</p><p>You can use a wide flat-headed screwdriver to force the two "halves" apart to easier slide the nut in place if needed.</p></div>

How I Designed This

I just edited the file in Tinkercad
