◆ Candle wax
A white avocado half candle: the cut face, the skin lip and the round pit. A rigid two-part print, pour the wax straight in.
An avocado candle 91 mm tall: a real avocado cut in half, standing on its wide end. The flat cut face has a thin skin lip standing just proud of the flesh, the pit sits in the wide part as a smooth ball about half out of the flesh, the neck leans a little and a short stem nub finishes the top. The back is the smooth, rounded skin.
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 cut face looks straight out of the front half and the skin out of the back one, so nothing hooks, and the tool's own seam check finds nothing stuck. No silicone needed.
Shown poured in white, which lets the shape do the work: it looks like a ceramic piece on a kitchen shelf or a brunch table. Pour it in a soft green and paint the pit brown for the full fruit instead. The zip carries both halves, the avocado 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, open the halves at the pry pockets and trim the wick. Paint the pit brown and the skin lip dark green if you want the full fruit.

Pour the whole avocado in white or a soft green, then paint the pit with brown candle paint and the raised skin lip with a darker green once it is out. The pit and the lip stand proud, so a small flat brush stays on them easily.
Yes. It stands on a flat base at the wide end, with the cut face looking forward. The wick comes out of the narrow top, so it burns down from the neck like any pillar.
A plain white or cream pour reads like a ceramic ornament, and the pit and skin lip catch the light on their own. Colour works just as well: a soft green with a painted brown pit is the classic look.
