This is a 6 elix trapezoidal thread screw, it's pretty fun to play with and shows the capabilities of 3d printing.
It can also be used to test out your printer calibration on thight tolerance.

There are three files, they differs on the tolerance that the thread have 0.4 mm 0.6mm and 0.8mm.
If you don't know how well your printer is calibrated i'd start with the 0.8mm.

This model have to be printed with support enabled, so it can print the nut (on cura 70% overhang support).

Update:
v1.1
added a chamfer to the nut
all STL are now oriented in the correct printing position
added STP file for easy remixing

4/2/21
added longer screw
added thighter and looser tolerance version of both long and normal bolt both STL and STP
