Public-data experiment

Find a starting point for technical research.

A small collection of hardware repositories and research links. Follow the source to evaluate design files, licenses, methods, and fit.

Hardware repositories

Three selected examples, not a comprehensive index or popularity ranking. Inspect the files and license terms before reuse.

prusa3d/Original-Prusa-i3

Original Prusa i3 MK2 3D printer printed parts

License metadata: GPL-2.0

One search with up to five works. Search matches do not establish engineering suitability or commercial readiness.

Sources and access

GitHub

Public metadata. Bounded unauthenticated pilot; repository activity is not quality or adoption.

OSHWA

API key registration required. Not connected. Certification concerns openness, not safety or performance.

OpenAlex

Free allowance. One anonymous query in this pilot, with no paid key. Follow original papers for findings.

NSF awards

Public award search and downloads. Browse directly in this pilot. Historical awards are not open calls.

NIST NVLAP

Public laboratory directory. Check the facility's current method scope. No automated collection here.

DigiKey

Production access requires account, organization, and OAuth setup. Not connected; use the shortage tracker first.

Coverage and collection health

Three allowlisted repositories; one anonymous OpenAlex query with at most five works. Metadata and links only.

  • GitHub: Collected three allowlisted repositories (2026-10-06)
