convertSTL.exe for Windows

[vmario89]

Hi, just a quick note on converting that script into some native windows executable

Download Ruby (https://github.com/oneclick/rubyinstaller2/releases/download/RubyInstaller-2.7.0-1/rubyinstaller-2.7.0-1-x64.exe) Then run "cmd"

gem install ocra
git clone https://github.com/cmpolis/convertSTL.git
cd convertSTL/
ocra convertSTL.rb

It will generate convertSTL.exe

That's it. Super easy but helpful to de-force users to install Ruby in their system.
