A truly excellent plugin, thank you Aldo.
For those having difficulties making it work, this is what I did to make the Measure Tool plugin work in Cura 4.0.0:
Go to:
https://github.com/fieldOfView/Cura-MeasureTool/
Click on green “Code” button on the top right
Select “Download ZIP”
Wait for it to download
Unzip the file
Rename the folder “MeasureTool”
Put the folder in:
Mac:
/Users/*NAME*/Library/Application Support/cura/4.0/plugins
Win:
C:\Users\*NAME*\AppData\Roaming\cura\4.0\plugins
This is how I install all Cura plugins, since trying to do it via the website doesn’t always work.
