There are 2 versions of the coaster:
-The first version has the logo raised from the base with or without support lines.
-The second version has a 2mm tall base with the logo recessed by 1mm.

Please post a picture if you make one, I'd love to see that my coasters are being made and used! Thank you and enjoy!

The coaster measures 100mm in diameter by 3mm tall. The base is 1mm tall, the image is 2mm tall, and the brim is 3mm tall.

I would not recommend printing in black or white as those colours will wash out the effect. Grey, blue, red, or a similar shade of filament works best. Don't adjust the height as it ruins the translucent effect, even a base height of 1.5mm is too thick to let enough light through.

There are several files available to download depending on your preferred print settings:

No Lines / With Lines: Depending on your preference, the coasters have 2 versions, with or without lines. I suggest using the version with lines because it adds extra support for your drink on the sides.

Coaster: This is the complete design if you want to download and print it easily (at the cost of some print quality and potential scarring).

Coaster Top & Coaster Base: If you want the best quality, download these files. In your slicer software, stack the Coaster Top on top of the Coaster Base (raise the height of the Top by 1mm). In your per-model settings, enable ironing for the top so the image and the brim are ironed, and turn off ironing for the base. Ironing the base doesn't look good due to the fine detail your printer needs to iron around, resulting in a messy and often scarred base. A non-ironed base looks significantly better.

I have found that these settings in Cura result in the best prints without scarring:
-Z Seam Alignment: Sharpest Corner
-Seam Corner Preference: Smart Hiding
-Monotonic Top / Bottom Order: Enabled
-Monotonic Ironing Order: Disabled
-Combing Mode: Not in Skin

It took me 10+ failed prints before I found the best way to print these coasters. Trust me when I say the extra effort is worth it when you see them come out perfectly.
