Fit and Clearance Calculator
Calculate mating-part dimensions and a three-step clearance test ladder.
Fit type
Model dimensions
Total clearance, mm0.25
Shaft diameter, mm20.00
Hole diameter, mm20.25
Test clearance ladder, mm0.15 · 0.25 · 0.35
XY correction changes the hole after your calibration test. Print the ladder before a batch: shrinkage depends on material, orientation and printer.
About this tool
The tool turns a chosen fit into shaft and hole dimensions. Add your XY-calibration result, then use the three-clearance ladder to check your material and printer before producing a batch.
Useful for
- Design a lid, pin, hole or moving connection.
- Print a tolerance sample before a batch of parts.
Frequently asked questions
What is XY correction?
It is the measured difference between a model and a printed part; it adjusts the hole size.
Why may parts still not fit?
Accuracy depends on printer, material, orientation and temperature. Test the ladder with your profile.
