Why eight small pockets
Cosmetics are many small cylinders and flat discs, and in an open drawer they roll into one heap. Pockets fix that only if they are small enough that things stand up or lie one deep. Each pocket here is 38.5 mm wide and 58.2 mm from front to back inside: a nail polish bottle stands in it, a few lipsticks stand together without falling over, a small pot lies flat, a larger compact stands on edge against a divider, and tubes lean in a corner. Brushes and pencils are too long for it; give them a second tray with one compartment across and the full width as length.
What to measure
Vanity and bathroom drawers are shallow, so height is the measurement that decides. With the drawer nearly shut, read the clear height at the front edge of the cabinet, and keep the tray 3 mm under it; 40 mm suits a drawer with 45 mm or more. Then measure your tallest item that should stand. If the drawer is too low for bottles to stand, drop the height to 25 mm and lay everything flat. For the footprint, measure width and depth inside the drawer and divide: two trays of 160 mm fill a 322 mm drawer with a millimetre to spare at each side.
Wall, floor and material
Everything is 1.2 mm: walls, dividers and floor. The contents are light, and thin dividers leave more room in the pockets; the three dividers across and one along the length also brace the outer walls every 40 to 60 mm. Material choice here is about cleaning. Powder and foundation get into the fine grooves between layers, so print the walls at 0.12 to 0.16 mm layers for a smoother surface that wipes clean. Keep nail polish remover away from the tray: acetone dissolves ABS and ASA and can dull or soften other filaments.
Printing
Print with the floor on the bed, no supports. Eight pockets mean the nozzle crosses open space constantly, and any stringing shows as fine hairs across every pocket, which matters more on a tray that is on display than in a toolbox. Dry the filament and lower the nozzle temperature by 5 to 10 degrees before starting. A light colour shows spilled powder and makes small dark items easier to find.
