# Screw Tolerance Tester Test how tight your tolerances are for screws. Can test from 0.0 - 0.2. The screws and nuts are M10 1.5. # Update 22 February 2022 Added a second generation of files, the originals text was too small to print . The G2 pieces are slightly bigger and take a little longer to print ( by minutes) but you can see what the tolerance that has been applied to each piece. ## Guide to Models ### Screws Print one or both.. Screw - 0.1mm Tolerance Screw - 0.0 Tolerance ### NutPlates You can either print the 5 in 1 test, or the individual torances you require. I think the 5-in-1 is a good place to start, then you can print the individual nutplates as you callibrate your machine. NutPlate - 0.0 - 0.10 Tolerances Nut- 0.0 Nut - 0.0125 Nut - 0.025 Nut - 0.05 Nut - 0.10 ## Tolerances A tolerance has been applied to each of the 4 faces of a screw and also the threads. The total tolerance will be the sum of the tolerance on the screw + the tolerance of the nut. Therefore if you are using the screw 0.10 and the nut 0.10 the total tolerande is 0.20. ## Getting tighter tolerances If you are having trouble with tolerances not been great enough, i suggest doing both Silcer Flow and E-Step calibration for each filament you print with. Use the really useful guide from Teaching Tech, the link is below. ## Teaching Tech Callibration Guide https://teachingtechyt.github.io/calibration.html
