Old Sinclair DINO Gasoline logo coasters. 

I'm still pretty new to 3D printing and while this print profile worked fine on my X1C, you might fine better setting that will work for you.

These coasters are 100mm in diameter and 3mm thick.

I put 4 x 4 Inch Self Adhesive Cork Round Backing on mine that I get from Amazon. I have attached the link. https://a.co/d/2IuGUCU

I would greatly appreciate it if you could take a moment and rate my models and profiles, Thanks
