Sample 259 KB STL File — Free Download for Testing
sample-model-low-poly-ascii.stl · 258,568 bytes · 1,024 triangles · 3,072 vertices · normals · millimetres, Z up
This is a 259 KB sample STL file — exactly 258,568 bytes, generated by us rather than scraped, so the size is deliberate and the contents are free of anyone else's copyright. 1,024 triangles • ASCII • torus knot 65 × 68 × 32 mm • 259 KB (1,024 triangles · 3,072 vertices · normals · millimetres, Z up). Use it to test an upload limit near 259 KB, to time a transfer, or as a fixture whose hash never changes.
Sizes here are decimal: 259 KB means 258,568 bytes, not 0.25 MiB. If your limit is expressed in binary units, check the exact byte count above before assuming this file is under it.

Frequently asked questions
How big is this STL file exactly?
Exactly 258,568 bytes (259 KB using decimal units, where 1 MB = 1,000,000 bytes). Binary-unit tools will show a slightly different number: 0.25 MiB. The SHA-256 on this page lets you confirm you received the same file byte for byte.
What can I test with a 259 KB STL file?
Upload size limits that sit near 259 KB, transfer timing, storage quotas, and any pipeline that behaves differently above or below a size threshold. Pick the file just under and just over your limit to find out whether the limit is inclusive.
Is this file free to use commercially?
Yes. It is generated from scratch by our own open script — no third-party copyright, no scripts or macros inside — and free for any purpose including commercial products and redistribution, with no attribution required.
