About the data

• Sources. Every part links to its original Printables, Thingiverse, MakerWorld or Cults3D listing. We credit the designer shown on that listing and don't host files.
• Material and hardware appear only when the listing states them, or when the platform's print profile shows a material, which we label "print profile". If neither does, we say so.
• Fit status. No part has been test-fitted by CrawlWorx yet. Reported means the designer or reviewers say it was run on that chassis. Unverified means nobody has confirmed the fit.
• Gearing. Stock ratios come from manufacturer manuals and pages, cited on the calculator. Derived or community numbers are labelled estimated.
• Links were checked on 16 Oct 2026. Listings change, so if one breaks, the newsletter is the place to tell us (coming soon).
