A pipe ashtray with tray for two pipes.
The two trays are designed so that even top-heavy exemplars or small travel pipes do not fall out and have a secure hold. The ashtray has rounded corners and edges for easy cleaning.
For knocking out the pipe is a recess for a cork provided. For this purpose, a simple wine cork can be cut and glued.
Use heat-resistant filament for printing. ASA or at least PETG is best.
