◆ Candle wax
A 70 mm cube candle carrying the eyes of Michelangelo's David, from a museum scan. A rigid two-part print, no silicone.
A cube candle 70 mm on every side, its edges rounded to 5 mm, with the eye region of Michelangelo's David rising out of the front face: the heavy brows, both eyes and the top of the nose, 66 mm across. It is the classical, Renaissance look that fills candle boards on Pinterest, cut down to a shape that stands square on a shelf.
The relief is not a remodel. It is cut from SMK's 3D scan of a plaster cast of the Head of David (object KAS2232 in the Royal Cast Collection of the National Gallery of Denmark), which SMK publishes under the Public Domain Mark, so you can sell what you cast.
The mold is exactly what our two-part candle mold generator builds for it: two rigid halves with rubber-band grooves, pry pockets and a pour funnel on top. The relief rises out of a flat face that pulls straight away from the front half, so the brows and lids come out as sculpted, and the tool's own seam check finds nothing stuck. No silicone needed.
Pour it in white or bone and it reads like a piece of plaster from a cast gallery; a soft grey or terracotta suits it too. It pairs with the David lips cube. The zip carries both halves, the cube master as its own STL, the tool's own print-settings sheet and a recipe file for the generator.
Shown as a 3D render of the printed mold halves pulled apart around the candle they cast, not a photo.

Print both halves as exported. Clamp-strength settings: 4 walls, 40% gyroid infill, no supports.
Drop a tabbed wick into one half so the tab sits on the cavity floor, close the halves and band them along the whole seam.
Clip the wick centred across the pour funnel and pour at 65 to 75 C.
Once the first pour is firm but still warm, top up the funnel. Wax shrinks, and the second pour fills the dip.
Cool fully, then open the halves at the pry pockets. The eyes come out of the front half. Trim the wick and buff the seam round the sides with a nylon stocking.

It is cut from a 3D scan of a plaster cast of David's head held by SMK, the National Gallery of Denmark (object KAS2232). Casts like it were taken from the marble for art academies. SMK releases the scan under the Public Domain Mark, so the relief and your candles are free to use and sell.
The eyes and brows rise out of a flat front face and every part of them faces the way the front half pulls away, so nothing hooks the print. The tool runs a seam check before it builds the mold and found nothing stuck. Pour at the low end of the range for the crispest lids.
Pour it white, let it cool fully, then dry-brush a little grey or brown mica mixed with a drop of melted wax into the creases round the eyes and wipe the high points clean with a paper towel. The brows and lids stand out like an old cast.
