Linealanschlag - Rulerstop

Edit: Some people had issues, printing the trapezoid threads, added a version with regular M14x2 threads.

Just in case, one might think, that does not work.... ;)

Does, what it looks like.... for Ruler 30 * 1.0 mm.
The printing of that part in order to produce working threads was challenging.

Important:

IN ORDER TO PRINT THE THREADS, YOUR PRINTER MUST BE CALIBRATED REALLY GOOD !!! Accept the challenge! ;) it is worth the effort, after that, your printer works dimensionally accurate.

My calibration sequence (sequence is impotant) is:
-Take care, that your printer stands on level subsurface
-Take care, that the ground/subsurface does not shake, while printing
-Take care, that the printer is built and alligned exactly
-PID tuning http://marlinfw.org/docs/gcode/M303.html
-optimally levelled bed, at least, first layer without elephant foot.
-calibration of extruder steps and correction in firmware or start GCode
