Hi, this is my first model. Sorry, I messed up the dimensions.

I did export it carefully, and it was fixed with a mesh net.

The dimensions that I found most suitable for printing this are X-100 mm, Y-100 mm, and Z-5 mm.

When editing the Z axis separately, please turn off the aspect ratio lock. We don't want the coasters to be too thick.

You can put small cups in the middle. Have a great time printing!
