That's a small singing gingerbread man for the Christmas tree. Just press left leg and it sings pre-recorded sound. Consists of two parts. You can assemble them with 3xM4/8 normal screws or use a glue-gun (just close the wholes in any software you're using).

It's providing pretty ok sound for the price. Plus, you can record it as many times as you like.
There's a small vertical slot on the back - I kept it for the battery isolating film. We're planning to send the Singers as gifts to our family and friends and just to save a battery charge, it's batter to keep it before use. If you don't need it, again feel free to remove it. Hope you would like a result.
I printed it with my Prusa i3 MK3 with 0.4 mm nozzle at 0.2 layer height, 10% infill. No supports required. To achieve double coloured top panel, simply change filament to the desired colour after 2 mm printing.
Merry Christmas and Happy New Year!
