PrintLister

About

PrintLister turns the models you already love from stl sites into Facebook Marketplace listings in one click!

If you sell 3D prints, you know the grind: find a great model, check its license, figure out a price, write a title and description, grab a photo, then copy-paste all of it into create-listing forms. 

PrintLister does that for you!

HOW IT WORKS
1. Browse stl sites like normal. PrintLister adds a "+" to every model card and detail page.
2. Click the "+". A side panel opens with a suggested price, a plain-English license check, three photo options, and an auto-written listing.
3. Hit "Open in Marketplace & fill." Facebook's official "Create listing" form opens, pre-filled with your title, price, description, and photo. You review it and click Publish.

WHAT YOU GET
- The "+" on every model.
- Auto price estimate with a low–high band, based on comparable sold items.
- A passive license / IP flag (green / yellow / red) so you can avoid listing personal-use-only or branded models.
- Three photo options: the model's own image, upload-and-enhance your own, or a generated marketplace-style shot.
- A listing composer that writes the title and description and drops them into form.
- A "Currently Selling" dashboard with view counts and one-click "send to printer"

BUILT TO KEEP YOUR ACCOUNT SAFE & PRIVATE
- The human always publishes. PrintLister fills Facebook's official form and opens it, nothing is ever posted silently.
- No credentials, ever. It only acts inside your already-logged-in browser session. It never sees or stores your Facebook password.
