This is the way. They have a image generator too

The head might be too close to the bed. You could potentially compensate with either additional top layers in the slicer or just give it some more room to lay down layer one. Another possible cause is potentially too much heat. I am going by the slight elephants foot at the bottom of the cube and the slight droop at the top of the X and Y.

If you ask me it should have been the cob. Not the kernel.

Just wanna add here that it is not just hurt in terms of time, money or loss of data(those are a given). It could even land you in legal trouble that you can not explain your way out of in some extreme circumstances.

If you are starting with nothing then maybe a lithophane conversion on the photo

Just some options. 3dp.rocks works well from my experience. That would at least give you a starting point. I’d see if there is some way you can scale it on the z axis of the features are point straight up to get more depth on what the lithophane provides.
