A maxed-out-bed advent calendar with 25 print-in-place doors. The individual cubbies are large enough to just fit a square of Ghirardelli chocolate or a Ferrero Rocher.
The doors open and close with a satisfying click and are not prone to accidentally popping open. You'll need to use a coin or the end of a butter knife to open the doors the first few times, but after it's worn in a bit, a fingernail works fine.

You can make the outside of the box a single color to greatly improve print time.

Colors

I make use of layering to different colors to get the proper effect. I highly recommend using the same colors to make sure the graphics come out ok
All filament is Bambu PLA Basic:

• Jade White
• Black
• Red
• Bambu Green (not the “Green” from Bambu that's more of a dark blue)

This model makes for a VERY full bed, you will need to reduce the purge tower brim width to 1mm and watch the print to remove the front purge line and calibration lines as soon as they're done (the rear purge line is fine).
