dice tower 3d model

Create a 3D-printable Feywild big-top dice tower about 10 inches tall. Include a top opening sized for standard dice up to 25mm, an internal spiral chute for random rolls, and a lower exit leading to a wide containment tray. Ensure all geometry is manifold, watertight, and solid for STL export. Focus on smooth dice flow, accurate functional clearances, and stable base design. Subtle whimsical tent form, but prioritize structural clarity and seamless spiral alignment.
