Make the finished part obvious
A strong listing shows the actual printed result, the scale of the object, and the intended use without making users guess.
Use photos or renders that help people understand the model quickly, especially for functional parts where dimensions and orientation matter.
Document print assumptions
Mention material, nozzle size, supports, orientation, and any fit checks that matter. Clear assumptions reduce failed prints and support questions.
Compare changes over time
Creators should track listing improvements, downloads, boosts, and profile changes as experiments. The goal is to learn what makes a model more useful, not only what makes it more visible.
