Qwiktune, how did your cal squares turn out? I set up my printer up for PETG and took a few photos of the calibration squared and if you click on the thumbnails there is more info under the big pictures https://misc.airscapesart.com/calibration/index.html

I printed your part but forgot to enable support, second copy is printing now. Will post photos when it is done. If you live in the US I would be happy to mail the part to you just in case you can not get this working on your machine.

BTW I am printing at .3mm not .2
