The model is 60 x 60 x 3.17. The bottom side has bars that connect the pinnacles to the ring. Print settings: 0.10 mm detail, 15% infill. No supports.
The print had a lot of fine “fuzz” when printed. I used a hairdryer to remove it. Just be careful not to move the model until it's cooled down.
I don't think an inkpad is the best medium to use for printing but that's what I had.
