Topic: Easy print calibration piece
Reading through the forum, I have noticed that people have asked for an easy to print calibration piece which everybody could use to help fine tune their calibration, and that other members could have the exact item to help suggest solutions to any problems.
Whilst surfing on the interweb, I came across this item on Instructables by Sardau which I think may fit the bill - Has helped me to fine tune mine. It also has a locating hole in the print to allow exact placement
It was originally 30mm high, but I have also built a 90mm high one as I was getting artefacts from the smaller one for some reason.
