I am a smoker but I only smoke outside or in my garage, where I spend a lot of my free time.
I only use ashtrays that don't smell but are unfortunately very ugly...
I've been thinking about doing something about it for some time now.
I made a remix of an existing file using Tinkercad (thanks https://www.thingiverse.com/cheesemcgee) so that it served my purpose and the end result couldn't be more metaphorical.
A Death Star!
The original ashtray is 75mm diameter and 95mm height.
