Chessie System Railroad Coasters
This coaster is 89mm square and 3mm thick. The settings worked fine on my X1C but you may fine settings that work better for you. I'm still pretty new to 3D printing so there could be better options then what I choose. If you print my coaster holder you may have to adjust the height depending on what thickness cork you apply to the back side.
I use these Self-Adhesive Cork Squares, 3.5 x 3.5 Inches from Amazon. They will have to be trimmed to fit the coasters.
I have provided the link to them. https://a.co/d/6O143Am
I would greatly appreciate it if you could take a moment and rate my models and profiles, Thanks
