Sign Maker v1.1.5

Sign Maker for SolidCraft, by Del (postmanpat).

Unofficial community add-on. Not affiliated with or endorsed by the SolidCraft maintainers.
SolidCraft is a separate install: https://github.com/tangency-labs/solidcraft/releases

Windows (x64)

Installer: run SignMaker-<version>-setup-x64.exe. It installs to Program Files\Sign Maker with a Start Menu shortcut, an optional desktop shortcut and an uninstaller (Settings > Apps). It asks for admin rights. The setup is unsigned, so SmartScreen may say "Windows protected your PC": choose More info then Run anyway.
Portable: unzip SignMaker-windows-x64.zip and run SignMaker.exe. Leave the _internal folder beside the exe.

macOS (Apple silicon, arm64)

Unzip and open Sign Maker.app. The app is unsigned: the first time, right-click it and choose Open.
This is not a universal2 binary. The GitHub macOS runner's Python is arm64-only, so an Intel + Apple silicon build is not produced. Intel Macs can run from source with run.command.

Linux (x86_64)

tar -xzf SignMaker-linux-x86_64.tar.gz then ./SignMaker/SignMaker. Built on Ubuntu. aarch64: run from source with run.sh.

macOS and Linux builds are new and community-tested. The author has tested Sign Maker on Windows.
