8mm Flanged Nut for Acme Lead Screw

thingiverse

EDIT A lot of people are adding this to collections called "Things to Make" or similar. If it's not clear from the image, this isn't a exact replica of the original part. The threads are missing because this is meant as a place-holder to be used in a CAD design, showing how it would fit or should be modified. It would be completely useless as an actual part, except perhaps as a lost-PLA master for a casting which would then be threaded manually. END of EDIT This is a mock-up of the brass nut included with 4-start acme threaded rods sold by several Ebay sellers. The dimensions were taken from a mechanical drawing posted on one of those listings. I've included the original Sketchup (ver. 8) model and an STL. The .SKP is in meters, for reasons known to most SU users, but the STL is in mm. UPDATE: There is also an anti-backlash version of this nut.
