Chimney Advent Calendar – 24 Days, Sweets Drop Into the Fireplace

🎄 Chimney Advent Calendar: a sweet drops down the chimney every day! 🎅 Hi everyone! 👋 I wanted an advent calendar that's actually fun to open, not just another paper door. So I made a tall brick chimney where Santa's treats really do come down it! 🍬 Every morning in December, you pull out that day's golden card. The sweet falls down the chimney, rolls through the fireplace arch and lands right in the hearth. My favourite part is watching someone's face the first time they pull a card. ✨ What I love about it ❤ - 🧱 One layer per day. The 24 layers snap together, so you can print a few at a time whenever your printers are free.

- 🔒 Cards click into place. A small spring holds each card, so nothing falls out by accident, but it still pulls out easily.

- 🔥 Sweets land in the hearth. A smooth ramp rolls every treat into the fireplace, where it stays.

- 🎨 No colour changes needed. The numbers on the cards are raised and the numbers on the chimney are sunk in. Brick red, gold and white look really festive together.

How big is it? 📏 About 60 cm tall, 116 × 117 mm footprint. Each compartment is 90 × 43 mm and fits sweets up to about 17 mm tall: chocolate coins, wrapped candies, gummies or small truffles. 🍫 What you'll print 🛠 - 1 × fireplace_base (I used white marble PLA)

- 24 × chimney layers (brick red) – layer_01 … layer_23 + layer_24_top

- 1 × chimney_top

- 24 × date cards (gold looks magical!)

- Optional: number inlays, if you want the chimney numbers in a second colour

My settings ⚙ PLA or PETG, 0.2 mm layers, 2–3 walls, 10–15 % infill, no supports. The 3MF is set up for the Prusa MK4 with everything laid out on 8 plates (about 960 g, 1 day 16 h). Filling it 🎁 - Put card 1 into the top of the fireplace and place a sweet on it.

- Snap layer_01 on top.

- Keep going (card → sweet → layer) all the way to layer_24_top.

- Put the chimney top on.

From 1 December, pull one card a day, starting from the bottom. 🎄 If you print one, please post a make! I'd love to see your colours and your Christmas setups. 📸 Merry Christmas and happy printing! 🎅✨ 3DSeisis 🇱🇻
