Resolving a specification before handing it to a factory

The brief

The client wanted an accurate execution of an existing design, delivered as editable STEP geometry for their factory. The brief combined a sculpted holder with a tube, adapters, cap and bubble-blower insert, but several dimensions were inconsistent.

How it went

Resolve conflicting measurements

I flagged a mismatch between a reference length and the written dimensions. I also identified that a 20 mm outside diameter and 15 mm inside diameter imply a 2.5 mm wall, rather than the stated 2 mm. The client clarified both points.

Build the component set

I modelled the sculpted holder and accompanying tube, cap, adapter and insert. I shared views and draft-angle screenshots, then delivered the parts individually and in a ZIP package.

Respond to assembly feedback

The client explained that the split holder still needed a connector arrangement matching their reference. I revised the assembly concept and supplied updated holder geometry.

Bring the documentation into alignment

I updated the instruction PDF to reflect the revised CAD and added factory-facing assembly notes. When the client had trouble downloading the STEP file, I re-uploaded it.

The decision I would defend

The value was in detecting ambiguity early and turning it into explicit dimensions, then keeping the CAD and the instruction document consistent after revisions.

Outcome

The client approved the milestone on 3 March and later asked about availability for another project. The delivered set included five initial STEP parts, a revised holder and updated instructions.

Delivered

• Five component STEP files
• Revised holder STEP model
• Updated CAD instruction PDF
• Review screenshots and packaged files

Scope and limits

The connector was a CAD proposal for factory review. Physical snap-fit testing, tooling approval and production performance are not established.
