Overview
glTF to STL Converter (gltftostl.com) is a free, browser-based tool that converts glTF 3D scenes into binary STL files entirely on your device. It prioritizes privacy by processing everything locally—no files are uploaded to a server. The tool is designed for 3D printing enthusiasts, game developers, and designers who need to prepare glTF models for slicers.
Mileage Log from Google Maps App (by MileageWise Inc.) is an Android app that transforms your Google Maps Timeline history into IRS-compliant mileage logs. It targets freelancers, gig workers, small business owners, and anyone who needs to track business mileage for tax deductions. The app offers a free preview but requires in-app purchases for full features.
While both are conversion tools, they operate in completely different domains: one deals with 3D geometry, the other with location data and tax documentation.
