This is a 23 KB sample 3MF file — exactly 22,754 bytes, generated by us rather than scraped, so the size is deliberate and the contents are free of anyone else's copyright. 3 objects, 3 colours (basematerials) • 2,248 triangles • 23 KB (2,248 triangles · 1,130 vertices · 3 objects · 3 materials · millimetres, Z up). Use it to test an upload limit near 23 KB, to time a transfer, or as a fixture whose hash never changes.
Sizes here are decimal: 23 KB means 22,754 bytes, not 0.02 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 3MF file exactly?
Exactly 22,754 bytes (23 KB using decimal units, where 1 MB = 1,000,000 bytes). Binary-unit tools will show a slightly different number: 0.02 MiB. The SHA-256 on this page lets you confirm you received the same file byte for byte.
What can I test with a 23 KB 3MF file?
Upload size limits that sit near 23 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.
