Classic T3
The current package is T3 v261019, a ZIP file: unzip it and run BrimloadT3.exe, no installer required. Opening saved plans works within one edition at the moment: it does not open plans saved by the Chinese T3 or by U3, and a plan saved by a newer version may not open in an older one. The trial runs on Windows 64-bit, does not need internet access, and is valid through December 30, 2026.

Windows 10 and 11, 64-bit only; no Mac or Linux package.
Version 0.1.1. Works offline. Valid through December 30, 2026.
