Vinyl Records Coasters

I'm sharing a 3D-designed coaster set in the shape of vinyl records! The set includes multiple options for printing flexibility:

Separate Parts: The coaster has a central part and a grooved part that can be printed separately.
Single-Piece Option: A one-piece model in a single color for a straightforward print.
Two-Color Print: A model designed for two-color printing—this is my first time creating a two-color file, so I'd appreciate any feedback on its effectiveness.
Additionally, I’ve included two different holder designs for storing the coasters.

Let me know if you try these out and how they work for you. Looking forward to hearing your feedback!
