# An STL draft needs a print check

> Use the saved vase example to see what one mesh check found, then assess your own file before slicing or physical production.

## Is a generated STL ready to print?

A downloadable STL is a draft, not print approval. One saved vase example contains 29,805 triangles. A local edge-incidence check with vertex coordinates rounded to six decimals counted 61 boundary edges and 31 non-manifold edges; those numbers describe only that file and method. Units, intended scale, wall thickness, slicer behavior, and a physical print remain unchecked. Inspect and repair your own result separately before production.

## Check the file before any print attempt

1. **Keep the original file and inspect the full shape** Download the STL, retain the source image, and rotate the preview to look for unintended holes, fused details, and distorted surfaces. The optional GLB render is another view of a job result, not a substitute for checking the STL.
2. **Establish units and scale** Open the STL in your modeling or slicing workflow and set the intended units and physical dimensions. The saved vase example has file-coordinate bounds, but those numbers do not establish millimeters, inches, or a usable size.
3. **Check closed and manifold geometry** Look for open boundaries, non-manifold edges, reversed faces, and intersecting parts. Our one-case check found 61 boundary and 31 non-manifold edges after coordinate rounding; it did not repair them. Even automatic slicer repair may miss issues, as [Prusa’s repair guidance](https://help.prusa3d.com/article/corrupted-3d-models-for-printing_2205) notes.
4. **Assess walls and small features** Measure wall thickness, the opening and base, and any narrow features against your material and printer requirements. No wall-thickness or strength test has been performed on the public vase result.
5. **Slice and review the proposed layers** Use an appropriate slicer to inspect the layer preview, supports, overhangs, and toolpath after any repair. The public vase has not been sliced or physically printed, so no print pass is claimed.

## What the published measurement means

The [home-page vase image](https://giftstlstudio.com/media/result.png) and its two angles depict the same saved mesh from one successful generation. Its 29,805 triangles and edge counts are local file measurements, not a test across other jobs or a certification of this vase. Rounding vertices to six decimal places affects how coincident edges are counted.

For choosing and submitting an input, see the [image-to-STL guide](https://giftstlstudio.com/image-to-stl-guide). The [home page](https://giftstlstudio.com/) shows the one saved illustration-to-mesh example; [pricing](https://giftstlstudio.com/pricing) lists the 200-credit draft cost. A new request still depends on current workbench availability.

## Before a physical print

### Do 29,805 triangles mean the vase is detailed enough?

Triangle count says how many faces are in this file. It does not prove correct dimensions, closed surfaces, printable walls, or visual quality.

### Will every new model have 61 boundary edges?

No. The edge counts are from one saved vase STL and one local rounded-coordinate check. They are not a prediction for other results.

### If my slicer accepts the file, is printing guaranteed?

No. Check scale, walls, supports, material, and the layer preview, then validate the physical result for your use case. A slicer accepting a file is not a print-quality guarantee.

### Does Gift STL Studio repair the mesh for me?

No mesh repair is promised. The workbench previews and downloads the saved result; inspect and repair it in appropriate modeling or slicing software.

## Start with an inspectable draft

Check the 200-credit quote in the workbench, then treat any returned STL as a file to inspect and refine.
