coaster tile 3d model

Create a 3D model consisting of two parts: (1) a square coaster base with a raised border, and (2) 25 small tile blocks designed to be glued onto the base. === Part 1: Coaster Base === - Total size: 120 mm × 120 mm × 4 mm thick. - Outer border: 3 mm thick and 2 mm tall, running around the entire perimeter. - Inner tile area: 102.5 mm × 102.5 mm. - The inner tile area must be flat. - Leave equal margins of 8.75 mm on all four sides between the tile area and the outer border. === Part 2: Tile Blocks (25 pieces) === - Each tile: 20 mm × 20 mm × 3 mm total height. - Tile border: 1 mm thick walls, 3 mm tall. - Inside the tile, create a recessed bowl-like cavity: - Recess depth: 2 mm. - Inner cavity size: 18 mm × 18 mm. - Bottom thickness of tile: 1 mm. - The bottom of each tile must be flat for easy gluing. === Assembly Intent === - The 25 tiles will be arranged in a 5×5 grid inside the 102.5 mm tile area. - Each tile area should be slightly larger than the tile (20.5 mm) to allow
