🚬 3D-Printed Beverage Can Conversion Ashtray with Lid 

✨ Key Highlights

1. Beverage Can Inner Liner Conversion: Eco-Friendly and Practical

Perfectly compatible with standard 245ml iron beverage cans such as Wangzai Milk and Coconut Juice. After finishing the drink, simply repurpose the empty can as an inner liner—turning waste into treasure while saving money and protecting the environment. The metal inner liner is heat-resistant, scald-proof, and fire-safe, providing a secure receptacle for cigarette ash and butts, thereby completely addressing the limitation of PLA and other filaments that cannot withstand high temperatures. It’s an ideal creative DIY item.

2. Lid with Spring Hinge Design: Prevents Ash from Flying and Ensures Hygiene

The integrated spring-loaded hinged lid opens and closes smoothly without sticking; paired with a sealed lid design, it effectively prevents ash from scattering and odors from spreading, keeping your desk or car interior tidy. The cylindrical body shape fits snugly around the can, ensuring a stable, non-wobbling structure that’s suitable for placement on desks or in cars.

3. 3D Printing Optimization: Beginner-Friendly and Easy to Print

The model has undergone professional structural optimization, featuring no complex overhangs and no need for additional supports. Common filaments such as PLA, ABS, and PETG can all be easily printed, with natural layer transitions and precise alignment of the can’s snap-fit and hinge mechanisms. Once printed, the finished piece can be directly fitted onto the iron can, making it easy for beginners to achieve successful prints on their first try. Custom dimensions are also supported to accommodate different can sizes.
