Air intake panels.
Working through
the details.
Getting the fit right took time at the workbench and close attention to the customer’s feedback. We stayed with the adjustments until the customer confirmed the sample fitted well.
The air intake panels documented in the project.
Taking the fit concern back to the workshop
The customer was developing a pair of air intake panels that needed to follow the shape of a mating body. We made a sample from the supplied 3D model and sent it for evaluation in the customer’s assembly.
When the customer reported that the fit needed adjustment, we asked for the assembly model. We wanted to understand the surface the panel had to meet and work on that relationship in our own workshop.
That meant taking the review beyond the individual part drawing. The customer’s feedback gave us a specific issue to investigate, and the additional assembly data gave us a way to examine it physically.
Our team stayed involved in the fit review rather than leaving the customer to work out the next modification alone.
Customer identity and identifying project details are withheld.
Making time for a physical assembly reference
Using the additional assembly data, we produced a white 3D-printed mating component. Making this reference took extra preparation, but it gave our team a surface against which to position the black panel and work on the fit directly.
Further feedback from the customer identified an area that still needed attention. We continued the review, looking at both the panel shape and the physical reference guiding our adjustments.
The work stayed focused on the same practical question: what did we need to understand or change so that the panel would sit correctly in the customer’s assembly?
Time spent
understanding
the difference.
The project notes mention 3D-printing tolerances as a possible explanation, not a confirmed cause. We kept the review focused on the observable difference and the customer’s required shape, without treating the mismatch as proof that either party’s drawing was wrong.
With the customer’s white sample at the workbench, we had a shared physical reference for the next adjustments. The team could compare the black panel against it directly and work through the curvature in detail.
Following the curvature,
one area at a time
Our workshop team worked patiently against the white reference, adjusting the black panel’s curvature and shape step by step. The time went into checking the surfaces together and refining the areas that needed attention.
The comparison photographs show the parts together at the intake opening and around the surrounding edges. Those close views make the care in the work visible: the team followed the shape around the part instead of relying on one overall view.

Front opening: comparing the black panel against the white reference.

Side edge: continuing the shape comparison around the part.
Workshop comparison images show the development process. They do not constitute a dimensional inspection report.
Following through
to a fit that worked.
After receiving the revised sample, the customer confirmed that it fitted well and expressed satisfaction with the result.
The customer contributed assembly information and a reference sample. We took those inputs into the workshop and continued the adjustments. That exchange kept the development moving towards a fit the customer could confirm.
For a customer developing a formed panel, it matters that the supplier remains available when there are details left to resolve. In this project, our support continued through the hands-on work and the customer’s review of the revised sample.
This outcome relates to prototype fit. Production repeatability, durability and airflow performance are outside the evidence provided for this case.
Working through
a panel-fit issue?
Tell us what the panel needs to fit and what you are seeing in the assembly. Share the part model and photographs, along with any reference sample you already have. We can discuss what needs a closer look and which references would help the next adjustment.
