I have made this ashtray for easy moving while keeping it small for easy storage if a car or at home. I have attached a handle in the middle that makes it easy to empty the ashtray out, its form fits nicely in the fingers when emptying it without getting dirty, I have tried this tray and I have not had any problems with it melting or deforming as long as you put mostly ash into it. The print is for PLA and does not require supports.
