What a top listing looks like

Open a model in MakerWorld's top 1% and the listing looks busier than most. It has a median of 4 photos, 11 tags and a 757-character description. The median MakerWorld model has 3 photos, 6 tags and 299 characters.

Getting into that top 1% takes 2,370 downloads. Here's what those listings have that the rest mostly don't, on MakerWorld and then on Printables. Each site is set against itself.

We studied 1,004,137 public models from MakerWorld and Printables, two of the biggest sites for sharing 3D printing files: 327,759 from MakerWorld and 676,378 from Printables. Every number here describes those models, not every model ever posted.

Profiles, tags and descriptions

On MakerWorld the biggest gap is print profiles. The top 1% has a median of 3, and 83.5% of those models have two or more. Across all models it's 14.9%. Tags nearly double, from 6 to 11. The description is 2.5 times as long.

Video doesn't follow the pattern. 1.4% of top MakerWorld models have one, a hair under the 1.8% of all models. Assembly guides are rare everywhere, 1.0% of models and 3.5% of the top.

On Printables the top 1% of free models starts at 2,006 downloads, and the same pattern shows up inside the site. Free models in its top 1% have a median of 4 photos against 2, 6 tags against 4, and 564 characters of description against 263. They're 2.0 times as likely to come with a G-code file, 18.7% against 9.2%.

Photos

On MakerWorld, 48.1% of models show two photos or fewer. That count is the design gallery only, so photos people post with their print profiles aren't in it. Listings with 10 or more photos are 3.5% of MakerWorld models and 10.4% of its top 1%.

On Printables, 53.2% of free models show two photos or fewer. Listings with 10 or more are 3.6% of free models and 11.1% of the top 1%. The two sites count photos differently, so each one is only set against itself.

Description length

Free Printables models with no description have a median of 30 downloads. Past two thousand characters it's 60. On MakerWorld, short descriptions under two hundred characters sit at 11 and the longest ones at 26. The two sites count characters differently, so compare within a site, not across.

Bare listings

Put the gaps together: one photo or none, three tags or fewer, and a description under two hundred characters. 13.2% of free Printables models are that bare, and 3.8% of its top 1%. On MakerWorld it's 9.4% of models and 0.9% of the top.

None of this proves a longer description earns downloads. These are plain medians. A creator who writes a long description probably also shoots more photos and slices more profiles, and may already have followers waiting. The numbers here can't pull those apart. Comparing each creator's own models gets closer to what a single listing feature goes with.

But if you're looking at a listing with one photo and a one-line description, you're looking at the kind of listing the top 1% almost never has.
