Screw Tolerance TesterTest 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 2022Added 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 ScrewsPrint one or both..
Screw - 0.1mm Tolerance Screw - 0.0 Tolerance
NutPlatesYou 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
TolerancesA 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 tolerancesIf 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.
