How do we fabricate a part that fits the evidence, survives field use, and tolerates real-world variance?
First step
Measure the mounting need to ±1 mm; print v1; test fit under load; document one tolerance change for v2.
What you will show
Fit-test report with photos, dimensional table, and reason for the v2 adjustment.
Local place context
Which sensor type matches your evidence question — and what calibration will you use?

Expected outcome
Fit-test report with photos, dimensional table, and reason for the v2 adjustment.
You will design and print a sensor mount that solves a real problem from your earlier investigation. Whether your printed mount actually improves sensor reliability — and what design choices made the biggest difference. Before-and-after reliability measurements, design notes, and photos.
Five ways you could investigate
Pick one to start — or write your own question. The AI mentor supports you gently inside your investigation.
Idea 1
Tolerance vs fit
How does ±0.2 mm tolerance change fit and function?
Start with this question →Idea 2
Print orientation strength
Which orientation survives the force your evidence predicts?
Start with this question →Idea 3
Iteration after failure
What failed in v1 — and what single change fixes it?
Start with this question →Idea 4
Material flex
Does flexible filament reduce breakage at the joint?

AI mentor (inside your investigation)
No separate mentor page — support appears in your investigation workspace. It starts gentle: short prompts about your research context, data, and analysis. You or your teacher can turn assistance off for unassisted work, or request more help when you need it. It also guides fabrication choices tied to your evidence.
