Skull Tumbler with Stainless Steel Insert

This Skull Tumbler features a 3D printed outer shell designed to hold a stainless steel tumbler insert. The exterior showcases a bold gothic skull with deep sculpted relief, smooth printable geometry, and strong surface definition, making it ideal for painting, metallic finishes, chrome effects, or dark fantasy color schemes.

The model is designed so the stainless steel insert slides inside the 3D printed shell, combining the durability and insulation of stainless steel with the creative freedom of a fully customizable printed exterior.

Perfect for makers who want a dramatic, high-end tumbler without sacrificing usability. The relief depth is optimized for clean prints and easy post-processing such as sanding, priming, painting, and clear coating.

Features:

• 3D printed outer skull shell
• Designed to fit a stainless steel tumbler insert
• Deep, paint-friendly gothic relief
• Smooth geometry for reliable printing
• Scalable to fit different insert sizes
• Ideal for fantasy, gothic, and skull-themed finishes

Great for personal use, gifts, or custom-painted display tumblers.

Painting Tip: Start with a solid black undercoat to enhance depth, then lightly dry-brush silver over the raised details to bring out the skull texture. Accents were added using Cerulean Blue for contrast. For the final finish, apply a 1:1 craft resin clear coat, which creates a high-gloss, mirror-like surface with a realistic silver effect while also making the tumbler water-resistant.

Finish Note: The resin clear coat provides a high-gloss, durable, water-resistant finish suitable for everyday use. Hand wash only. Not dishwasher safe.

When fitting the stainless steel tumbler, push it down as far as possible for a secure fit. The stainless steel insert is the drinking surface and should not be painted. Only the outer 3D-printed shell is intended to be painted.
