💀 Four skulls, one cone, a river of smoke

 💀 Four skulls, one cone, a river of smoke.

 A gothic stone fountain for backflow incense cones. Place a cone on top: the smoke sinks into the

 ornate flask, splits into four equal channels and pours out of the open jaws of four skulls, flowing

 down into the fountain basin like a ghostly waterfall.

 ⚙️ HOW IT WORKS

 • The cone sits on the amphora-shaped top, on a metal washer glued to it (the washer protects the

 plastic from the heat)

 • A 5 mm hole leads the smoke into a small spherical chamber inside the flask

 • The chamber divides the smoke into 4 hidden channels (5 mm), all joining the sphere at the same

 height, so every skull gets its share

 • The channels run down inside the stone block and open into the skulls' mouths

 • Everything goes downhill: no fans, no tricks, just gravity

 📦 WHAT'S INCLUDED

 • 2 STL parts: fountain top (flask, arches, skulls) and base (basin with column)

 • Simple box joint: the base has a 20 × 20 mm peg that fits into the socket under the top

 📏 SIZE

 • About 150 × 150 × 133 mm assembled

 • Top: 74 × 74 × 90 mm. Base: 150 × 150 × 50 mm (fits a 256 × 256 mm bed)

 🔩 YOU ALSO NEED

 • 1 metal washer, about 16 mm outer diameter (M8): the only part to glue, on the 15 mm flat top

 • Backflow incense cones

 • No glue needed for the two parts: the top simply slots onto the base (a drop of glue only if you

 want it permanent)

 🖨️ PRINTING

 • Print profile included: it's the one I used for the fountain in the video, so just load it and

 print. If you change settings, keep an eye on the supports (see below)

 • Both parts print upright on their flat bottom: the top on its square base, the base on the basin

 floor

 • Supports only for the skull jaws, the arches and the gargoyles. Check the sliced preview: no

 supports must end up inside the smoke channels

 • PLA works; PETG is better if your room gets warm. The cone never touches the plastic thanks to the

 washer

 🔥 TIPS FOR A NICE SMOKE FLOW

 • Put the cone right on the hole and keep the burner away from drafts, fans and open windows

 • If one skull smokes less, blow gently through the top hole: dust or a print string may be blocking

 the channel

 • Clean the channels from time to time: incense resin slowly builds up inside

 ⚠️ Never leave burning incense unattended. Place the fountain on a heat-resistant surface, away from

 children, pets and anything flammable.
