Your build can teach more than a cover.

Record the original page, creator, licence and file version when available. If there is no version, record the download date and exact filename. If you organised or renamed your copy, keep its mapping to the original so someone else can locate the same part.

Printing a design does not make you its designer. Distinguish the source design, a permitted adaptation and your assembly photographs. Each contribution has its own authorship. When sharing modified files, first review the conditions of the model they come from and preserve the corresponding credits.

Record the printer and material used, nozzle diameter where applicable, layer height, orientation and supports. Include settings that affected the result without filling in details you no longer remember. An unknown field is more useful than an invented number.

Separate the slicer's estimate from observed time and weighed material. If you have not weighed the part, do not present an estimated mass as a real measurement. Explain what you changed from the creator's recommendations: the difference can help interpret both a good result and an issue.

• File and variant identified
• Known machine, material and settings recorded
• Estimates separated from real measurements

Start with a general view of the result and add details of important areas. Use your own photographs, sufficient light, a simple background and focus that makes the surfaces visible. You do not need a studio: you need an image that explains the part's condition and its relationship to the assembly.

To show a dimension, place the ruler or reference in the same plane as the area observed and reduce perspective. A photograph supports a measurement; it does not replace it. Show joints before and after assembly when that helps explain a clearance, mounting point or modification.

Describe your assembly order, fasteners and components. For RC, identify the chassis or component variant where relevant. Include critical measurements you checked and state whether you needed to sand, drill, reinforce or change a part to make it fit.

Keep the originals and record modifications separately. A successful result in your build does not guarantee it works on every similarly named platform. State precisely which combination you tested and avoid extending that conclusion to components you have not used.

Warping, an overly tight joint or a support that is difficult to remove can teach a great deal. Explain what happened, where and under which conditions. Do not automatically attribute the cause to the file: orientation, material and configuration are also part of the test.

If you repeat the print, record the changes and keep the earlier result. Changing several things at once can improve a part without establishing which change solved the problem. Describe the improvement without claiming a cause you have not isolated. A completed print is not itself a strength or lifetime test either.

When documenting a print, gather the model reference, your photographs, known settings, outcome and changes. If publishing your own design, include its files, dimensions and instructions as well as the licence. A cover alone does not give someone else what they need to build it.

Public collections help people discover related references while retaining each model's authorship. Finish your documentation with what you would repeat and what you would do differently. That small reflection turns an individual print into a useful experience for the next project.
