Straight 3D Models: Fittings, Gears, Ladders, Rails

«Straight 3D Models: Fittings, Gears, Ladders, Rails»

Straight threaded fittings appear in several combinations: male-to-male, male-to-female and female-to-female, sometimes assembled from three pieces. Straight gears, hinges and brackets belong to mechanical and furniture work, while ladders, rails and track sections serve access or hobby layouts. The main differences between them are the connection type, the thread or profile standard, and the number of parts in the assembly.

On the author's model page, look at the dimensions and scale first, then at the thread or profile standard if the part has to connect to something else. Check how many parts the model contains, how they join, and whether the author notes that supports are needed. The material and print settings listed by the author, together with photos of real prints, tell you more than a render does.

To widen the search, try synonyms such as in-line, linear or direct next to the part name, and combine them with the standard or size you need. Related topics include adapters, couplings, racks, rails, brackets and clamps. Searching by the connection type instead of the shape often returns more results.
