This is a print-in-place Bambulab X1 Christmas ornament that does not require supports. ou need to rotate the model in the sliser The model features an opening door, allowing you to place something inside. It can be used as a 3D printer test. It's outside dimentions are: 4cm x 4cm x 4cm. I successfully printed this using a Creality Ender 5 3D printer and PETG filament. Please note that that you need to rotate the model in the sliser and you may need to apply a some force to open the door after printing.
