Espresso Patronum…

… inspired me to do a coaster set. I liked the word play of the particular coaster and was bummed,

that there is only one. So I created three more.

Print settings:

• I HIGHLY RECOMMEND printing the picture face-down, in my opinion it looks way better. There is a comparison picture as well.
  Nevertheless the 3mf file I included has them face-up, so you can verify first if everything is okay.
• Arachne as the wall generator is definitely recommended for the best results.
• For flushing volumes I used 95 from white to black and 280 from black to white.

Additionally:

I experimented with the top surface pattern and switched two of them to “concentric”.

While this looks good in the preview, the printed parts don't look as good as the standard “monotonic line”.
