Cigar adapter for ashtray

Cigar Ashtray Adapter – Universal Round Ashtray Attachment

This cigar ashtray adapter is designed to transform a conventional round ashtray into a functional cigar rest. Instead of purchasing a dedicated cigar ashtray, you can simply place this adapter on top of an existing ashtray and instantly gain a stable and elevated cigar support.

The geometry is optimized for typical round household ashtrays with a standard outer diameter range. The adapter sits securely on the rim while providing a wide, curved groove that safely holds cigars without rolling. This makes it ideal for indoor use, balcony sessions, lounges, or gatherings where only regular cigarette ashtrays are available.

The model was specifically created with practicality and printability in mind:

• Universal fit for common round ashtrays
• Stable resting groove suitable for different cigar ring gauges
• Drop-on installation – no modification required
• Cleanable design with smooth surfaces and minimal ash buildup

For best results, printing in PETG is recommended. PETG offers increased temperature resistance compared to PLA, improved durability, and better resilience against accidental heat exposure from ash or brief contact with a lit cigar. The material also provides slight flexibility, which helps the adapter sit securely on various ashtray rims.

Suggested print settings:

• Layer height: 0.2 mm
• Infill: 15–25 % (sufficient due to structural shape)
• Supports: not required
• Orientation: flat on build plate

This adapter is a simple yet effective accessory for cigar enthusiasts who want a functional solution without replacing their existing ashtray. It is also a practical object for hospitality settings, events, or personal use where flexibility and portability matter.
