The mechanical side covers pin headers in single and double rows, push-in rivets, clips and small locking parts, often modelled in several sizes so you can match an existing hole. Decorative entries go in another direction: hair pins shaped as animal or fantasy skulls, and pin-up style figures with separate bases. There are also larger handheld pin-art and fidget pieces, where the model is mostly a frame plus many identical moving elements.
When choosing, look at the dimensions the author lists and compare them with the part you are replacing or the space you have. Check how many separate pieces the model contains, whether they are meant to be glued or snapped, and whether the author shows the orientation and support placement used. Material and settings matter for thin pins: small diameters and long overhangs behave differently in resin and in filament, so read the notes before slicing.
If the results feel narrow, try synonyms and related terms: fastener, rivet, clip, dowel, connector, header, hairpin, brooch, lapel pin, pin-up figure. Combining a function word with a size or a theme usually narrows the list faster than a single broad query. You can also search by the object the pin belongs to, such as a jar, a socket or a car trim part.
