this is light and simple tolerance test:
simply screw the both piece together, count the number of thread left and with
(number_of_thread_left + 1) * (ToleranceStep (default = 0.2mm))
get the tolerance of your printer
properties:
the thread are simply a circle extruded along a spiral
contains 5 screw thread the bottom one start with a diameter of (10mm + ToleranceStep), then (10 + ToleranceStep*2) + ... +up to (10 + ToleranceStep*5)
the model is fully parametric, using freecad you can set the ToleranceStep easily in the spreadshit
