Coaster xếp chồng (stackable)

Update 10.02.2024:
Added a version with removable grid.
Two tolerances available:
- norm: Normal tight fit
- loose: 0.4mm tolerance
Use this with the body file.

Update 18.01.2023:
Removed name tag on 1st layer.
All coasters can now be color switched at layer 11 (0.2mm layer height)

Update 14.05.2022:
Added a smaller version with 8cm inner diameter.

Update 13.05.2022:
New version V2 now stackable! And backwards compatible with the original version.
P.S. No supports needed! Filament change at layer 11 (0.2mm layer height).
P.P.S. Scaling down will most probably mess with the stackability. (I didn't test it)

Simple coaster with a lip to catch spilling.
Inner diameter is 10 cm.
