Baby Teeth Keepsake Containers with Numbered Lids | Tooth Fairy Boxes

These compact baby tooth keepsake boxes feature threaded lids, fine fluted grips, and a tooth design on top. Use the numbered lids to organize teeth individually, or choose the recessed tooth-outline lid for a simple single-color print.

Included files

• Numbered lids 1–20

• Recessed tooth-outline lid

• One common body that fits every included lid

Approximately 30.6 mm diameter × 22 mm tall when closed.

Painting the numbered lids

Each combined numbered STL contains the complete lid as one closed solid:

• The tooth is recessed 0.01 mm below the lid face.

• The number is recessed another 0.01 mm below the tooth.

These shallow steps create boundaries for your slicer’s color-painting tools. View the underside of the lid to paint the tooth and number, then check the sliced color preview. Painting behavior depends on your slicer and selection settings.

For a simple single-color option, use the recessed tooth-outline lid, which has a deeper, visible design.

Please share a make! Your printer, filament, and thread-fit feedback will help others get good results. The ones in the main image were printed using a Bambu X1 Carbon, 0.4 mm nozzle, 0.2 mm layers, Bambu PETG HF for the black and white, Atomic Filament Teal for the lids. I did scarf joints on aligned seams, but painted some random seams around the threaded parts for a smoother fit.
