Functional 3D printing tool
3D Print Tolerance & Clearance Calculator
Turn the fit you want into editable hole and pin dimensions, then apply measurements from your own calibration print.
These are nominal model dimensions. Print behaviour can differ from your design dimensions. For an important fit, print a small test first.

Start with the plain-language intent. You can always edit the diametral clearance below.
Use measurements from your own calibration print

Formula: target printed hole = nominal mating-part diameter + desired diametral clearance. Modelled hole = target printed hole - measured hole error. Modelled pin = desired printed pin - measured outside error.
Assumption: calibration errors are representative of this printer, material, orientation and settings. This calculator does not guarantee that printed parts will fit.
