Include the source and export formats

STL is common for printing, but STEP can help with review when dimensions, surfaces, or product intent need more context.

Add production notes beside the file

Quantity, material, color, finish, deadline, customer use case, and packing expectations help prevent vague quotes.

Flag known risks before review

Mention thin walls, moving parts, tight fits, cosmetic surfaces, heat exposure, outdoor use, or previous print failures.

Proof path

See how finished marketplace listings support the manufacturing story.

Product pages with photos, prices, materials, lead times, and checkout details make the manufacturing promise visible to both buyers and creator leads.
