Khay đựng coaster - OceanOvalery

I created this model because I have some coasters collected but if you want to print the coasters like the one on the render, here is a brief tutorial:

First, add a cylinder and change the dimensions.

Remember to click the padlock to enable uneven scale.

Then just change the print parameters as you wish, in my case, I changed for no top and bottom solid layers,  5 perimeter, 0.1mm layer height and 25% gyroid infill. 

There is endless combinations you can try. 

If you make this, post here so I can see, I'm very curious.
