Thanks everyone. I raised the initial temp by 5 degree, and reduced the z-offset by 0.05mm. It looks great now
it is printing the fidget star now. Note, that each star has a thickness of 2 walls. The 1 corner is a little bad, because i took to much to time adjust the z-offset.
semi-related: would it count as piracy, if you reconstruct the 3d model from the 2d promo-images?
