Jan5 2023 Update to V2:
-Lowered the height of the black squares from 4 layers to 2 layers for less filament changes and quicker print time.
-Lowered the thickness of the coaster from 6.8mm to2.8mm
-Improvements to the print profile in the .3mf file
The coasters are 100mm in diameter and 2.8mm tall. I have the pattern upside down, but you can rotate them if you want. I have the filament set to generic PLA.
The profile is based off the standard .2mm preset, I added a few top/bottom layers, and a third wall.
If you download the .stl model files, make sure you check 'detect thin walls' in the strength tab
Filament used:
Inland True Red PLA+
Bambu Basic Black PLA
