All good ideas. I have been printing this rotor with a 5mm brim which I tape down after a few layers (when there is clearance to get past the moving print head). In this case, the PETG still came unstuck from the bed and the only thing keeping my part in place was the tape, but it was not enough to keep it from tilting with the nozzle. (Tried to upload a video, but G+ wouldn’t allow adding it to comments).
I will try kapton to improve on the bed adhesion.
I can see where the stick/straw stabilizers would be ideal for controlling wobble with TPU parts especially, on a Cartesian printer. It IS possible I’ll see a benefit too from this technique later on with PETG on my delta, but I gotta get past the first 2cm. I have printed similar parts in TPU already without supports on this printer .
