Rooftop Santa Advent Calendar, 24-Day Countdown

Boost Me🎅 Thanks for printing Rooftop! If Santa made your December countdown a little more magical, a Boost 🚀 helps me keep designing new holiday models. 📸 Share your print in the comments, I'd love to see it!🎅 Santa's way down the chimney, one gift a day Rooftop is a 24-day advent calendar. On 1 December Santa peeks over the top of a brick chimney, and every numbered gift you pull out lets him drop one step lower. On 24 December he lands in the glowing fireplace, just in time for Christmas.

✨ Why you'll love it

- 👀 A countdown you can see – pull today's gift and Santa drops 6 mm down the chimney; watch him through the window in the bricks.

- 🎁 24 numbered gifts – red boxes with a white lid, bow and number: odd days on the left, even days on the right.

- 🎅 Round 3D Santa – a chubby printed Santa with a big beard, black eyes, white cuffs and a pompom hat.

- 🔥 A cosy fireplace – stone walls, a wooden mantel and floor, a garland with berries, two stockings on pegs, bark logs and red flames that glow with a 38 mm LED tealight.

- 🏛️ A balcony on the mantel – a white balustrade with acorn finials and little striped parcels around the chimney.

- 🧱 One piece, no glue – the whole calendar prints upright in one piece; every colour is a whole-layer band, so the brick courses wrap all the way round.

- 🔁 Every year again – push the gifts back in and Santa is ready for next Christmas.

🎄 How it works

- The 24 gifts are sticks that slide through slots in the chimney: 1 at the top, 24 at the bottom.

- Santa stands on the highest gift. Pull today's gift and he drops onto the next one, 6 mm lower.

- On 24 December the last gift comes out and Santa drops through the open chimney into the fireplace.

📏 Size

- 108 × 84 mm footprint, 247 mm tall; Santa is 45 mm tall.

- Plate 1 is one 247 mm tall piece: it needs a printer with at least 250 mm build height (P1S, X1, P1P, A1).

🖨️ Printing

- 📋 One profile, 2 named plates – Fireplace, Chimney and Roof · Gifts, Santa and Stockings.

- 🎨 Colours as pictured – Bambu PLA Basic White, Brown (bricks), Cocoa Brown, Dark Green, Red, Black and Beige. 4 colours per plate, so one AMS is enough.

- ♻️ Low purge – plate 1 only changes colour between layers, in bands.

- ✅ No supports, no glue – the parts slot together.

- ⚙️ Settings – 0.20 mm layers · 2 walls · 15% infill · textured PEI plate.

- ⏱️ Print time – about 17 h for the whole calendar on a P1S (489 g of PLA, purge included).

- 🕯️ Optional – a 38 mm battery LED tealight for the fire.

💡 Tips

- Odd days go on the left, even days on the right.

- Let plate 1 cool on the build plate before you take it off.

- Next year: lift Santa out through the arch, push the gifts back in and lower him in from the top.

- Battery LED tealights only, never a real candle.
