3D Printing Files Guide: From STL to Local Slicing
A local-first guide to 3D printing files, STL downloads and VAULT print preparation.

What is a 3D printing file
Start by identifying the intent: finding files, choosing a format, planning a footprint or finishing a slice. VAULT provides a local index, manifest, previews and export paths; it does not replace licensing, original instructions or your own print judgment.
Choose a drawer or sustainer in the workbench, then verify S, M, L or XL, depth, height, roof and optional parts. A configuration change can change both the file list and the copy count, so do not reuse an old manifest.

In the slicer, check units, dimensions, orientation, first-layer contact, supports, material and printer envelope. One STL may contain paired geometry; file rows, object rows and physical pieces are not automatically equal.
STL, 3MF and ZIP formats

Keep the original folder, manifest, export date and slicer project together. When something is missing, check paths, source version and selection state before substituting or printing again.
Checking quantities after download

The workflow is local-first: the browser reads legally obtained models by path and original STLs are not uploaded. Batch export and slicing are better on a computer; a phone is useful for reading and checking.

Review the layer preview for missing pieces, overlaps, unsupported areas and unexpected colors. Test-fit a small part before a large batch, and trace file and configuration changes when fit differs from the preview.
