Final 3D Printed Tolerance Tester Workday

Focus question: How can a printed tester help determine future assembly clearances?

Mission Briefing

Today’s Plan

Use this page with the lesson presentation, your engineering notebook, and the tools or evidence assigned for Finalize the Tolerance Tester for Printing.

Learning Targets

  • Finalize the tolerance tester design.
  • Check labeled features, clearances, and print readiness.
  • Predict what data the tester will produce.

Success Looks Like

Your tester is designed to generate useful fit evidence, not just look complete.

Opening Prompt

What makes a tolerance tester useful for a future rocket assembly?

Connect your response to the decision, evidence, or quality standard required for Finalize the Tolerance Tester for Printing.

Reveal: useful CAD thinking move

It provides real fit evidence across multiple clearances or feature sizes so you can make a recommendation for the next assembly project.

Core Skill

What We Are Practicing

Key Idea 1

Tolerance testers help compare real fits, not assumptions.

Key Idea 2

A useful tester includes multiple sizes or clear labeled features.

Key Idea 3

The print should produce data for the next design decision.

Review fit types and clearance decisions while completing and checking the final tolerance tester.

Pause, replay, or open the tutorial in a new tab while you work. Follow the lesson requirements when the video uses a different example.

Lesson Interactive

Configure a Complete Clearance Series

Set the starting clearance, step size, number of tests, and labeling method for the final printed tolerance tester.

Clearance Generator

Class target: six labeled tests from 0.10 mm through 0.60 mm in 0.10 mm steps.

A useful tester must produce comparable, identifiable fit conditions.
Your Task

Finalize the Tolerance Tester for Printing

Complete the tolerance tester model and slicer preparation so each clearance can be evaluated consistently after printing.

  1. Verify the tester includes every assigned fit value.
  2. Label or organize the features so results can be recorded later.
  3. Run the CAD review and export checks.
  4. Prepare and submit the final print file using the class workflow.

Quality check: Every test feature is present, distinguishable, and ready to produce comparable fit evidence.

What You Will Submit

Tolerance Tester Submission

  • The final submitted tolerance tester print file.
  • A labeled screenshot identifying the tested clearance values.

Submission standard: Every test feature is present, distinguishable, and ready to produce comparable fit evidence.
