Summary

This is a coaster I made after teaching myself to use blender. It is nowhere near perfect but I decided to make it for my father. I just thought others might want to see it to take inspiration from it etc.

I would recommend printing at 20-40% infill just so that it has a nice feel to it.
After opening it in Cura you probably want to scale it by a lot. You may also feel the need to make it shorter to reduce print time and improve the overall look of it.
