Export Multiple STL — a small Fusion 360 add-in that saved me a lot of time

I made Export Multiple STL because I got tired of exporting STL files one by one.

When I’m getting a model ready for 3D printing, I usually have a design full of separate parts (bodies). And the workflow always felt the same: click export, pick options, save… repeat… repeat… repeat. It’s not hard, it’s just slow—and it breaks your focus.

So I built a simple tool that does what I wished Fusion would do in one step:

• You select the solid bodies you want.
• You pick a folder.
• It exports one STL per body, automatically.

That’s it. No complicated setup. No extra screens. Just a faster way to get a folder of STLs you can drop straight into your slicer, share with someone, or archive with a project.

How it works in practice

1. Open your design in Fusion 360.
2. Click Export STL → Export Multiple STL.
3. Select the bodies you want.
4. Click OK, choose a folder, and you’re done.

File names come from your body names, and if you have duplicates, the add-in automatically renames them so nothing gets overwritten (like Part.stl, Part_2.stl, etc.).
