Valentine Hearts Tumbler – Decorative Love-Themed 3D Printed Mug Wrap Design

Celebrate love with this Valentine Hearts Tumbler, a decorative 3D printed model featuring raised heart motifs, ornate scrollwork, and a classic ribbon bow wrapped around a cylindrical tumbler form.

Designed with soft sculpted relief and smooth, paint-friendly surfaces, this model is ideal for 3D printing, hand-painting, and finishing. The layered heart details create depth without excessive overhangs, making it suitable for both beginner and experienced printers.

Perfect as a Valentine’s Day gift, romantic décor piece, keepsake tumbler, or themed display item, this design works beautifully with metallic paints, antique finishes, or soft pastel color schemes.

Important Notes:

• Designed to be used with a stainless steel tumbler insert
• For hot beverages, PETG is recommended instead of PLA
• Epoxy adhesive is recommended for bonding the stainless insert
• Hand-painting and sealing will enhance the sculpted details

This design is ideal for fantasy lovers, collectors, and anyone looking to create a unique, handcrafted tumbler.

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.

If you plan to paint the exterior and use the tumbler for drinking, ensure the outer shell is properly sealed with craft resin. Use a straw when drinking, and hand wash only under running water. Do not soak, do not use detergents, and avoid prolonged water exposure.

I’ll be releasing more designs that use this stainless steel tumbler soon!
