# CrawlWorx > RC crawling hub: every printable upgrade for your rig, sorted by chassis, with a fit status on every part and the gearing math built in. A directory of 3D-printable parts for the Axial SCX10 III, Traxxas TRX-4, Axial SCX24 and Traxxas TRX-4M, plus a gearing calculator. Each part links to its original listing and credits the designer. No part has been test-fitted by CrawlWorx yet. Fit status is either reported (the designer or reviewers say it fits; not confirmed by us) or unverified (nobody has confirmed the fit). Material and hardware are listed only when the source states them. ## Pages - [Gearing calculator](https://crawlworx.com/gearing/): crawl ratio, TRX-4 front/rear overdrive, and wheel speed from KV, voltage and tire diameter.
