Cargo Ships, Lithophanes and Keychains: 3D Models

This collection gathers several unrelated strands that share similar wording: cargo and sci-fi ships, nebula lithophanes, name keychains, caricatures and charger holders. It is useful when you already know the shape you want but not the term other people use for it. Most entries are small enough for a desktop 3D printer, though the lithophanes and ship hulls can run larger. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

How this collection is put together

Polyzon assembles this collection from search results on the connected platforms. Repeats and models without a preview are removed, weak matches go to the end, and the rest keeps the search order. Models belong to their authors — check the terms on each model's page.

About the category

«Cargo Ships, Lithophanes and Keychains: 3D Models»

The models differ a lot in purpose. Ships and containers are display or tabletop pieces, often split into hull, deck and container parts. Lithophanes are flat panels whose thickness carries the image, so they are usually printed upright and lit from behind. Keychains and charger holders are functional items with a loop, a clip or a cradle, and caricature figures sit somewhere between a portrait and a toy.

When you open a model page, check the size and scale first, then the number of parts and how they join. Look at whether the author lists supports, layer height, wall count and material, and read the photos of real prints rather than the render. Thin lithophane panels and small keychain loops behave differently across materials, so match the filament to the wall thickness you see in the description.

If a search returns little, try synonyms and related terms. Cargo can be searched as container, freighter or sci-fi ship; a lithophane may be listed as a light panel or a photo panel; charger holders appear as cable organizers, docks or stands. Adding the device name, the print size or the word keychain usually narrows the list faster than a single broad query.

FAQ

Frequently asked questions

What is a lithophane and how is it printed?
It is a thin panel where the image is formed by varying thickness, so brighter areas are thinner. It is normally printed standing upright at a fine layer height and viewed against a light source.
Why do cargo ship models come in several parts?
Hulls, decks and containers are often separate so they fit a smaller build volume and can be printed in different colors. Check how the parts align and whether the author shows an assembled photo.
How do I find a keychain with a specific name or car model?
Search for the name or the vehicle model together with the word keychain, and try the local-language spelling as well. Many sets are published as one file with several variants.
What should I check before printing a charger holder?
Measure the device and cable, then compare with the dimensions on the model page. Look at wall thickness and whether the author notes the material used, since thin clips can flex or crack.
