A desk tray for used IQOS cartridges, with a small compartment to be filed with some odour-absorbent crystals like cat litter or such.
The grille is printed with 0 top/bottom layers, 15% gyroid infill and 4 walls. It's a bit oversized so fits snugly the tray's body. It keeps the absorbent inside when you empty the tray.
The body of the tray contains a 'piston' to make it possible to eject the grille from below in case you want to change the absorbent.
The body and the 'piston' is print-in-place, there is a 0.2mm thick wall connecting the two parts which can be removed with the support (see cross-section pics).
The cap fits snugly as well.

The design is inspired by Mister.D's Organizer Box.
