◆ Candle wax
A happy cactus with a little smile, two raised arms and a terracotta pot. A rigid two-part print.

A cactus candle about 100 mm tall: a ribbed saguaro with two arms raised on either side as if it is waving, a small sleepy smile with blushing cheeks, standing in a flowerpot with a rim band and a layer of soil.
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 arms reach out along the seam and the face looks out of the front half, so nothing hooks, and the tool's own seam check finds nothing stuck. No silicone needed.
A candle for plant people who kill every real cactus. Pour it green and paint the pot terracotta, or pour it all in one colour. The zip carries both halves, the cactus 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 pot terracotta and the soil brown if you like.

Pour terracotta first, up to the top of the pot rim, and let it skin over. Then fill the rest in green. Or pour it all in green and paint the pot with terracotta candle paint afterwards, which is quicker.
Straight up the middle of the trunk and out of its rounded top, where the pour funnel sits. The arms burn as the flame works down past them, so let a tall cactus burn in short sessions.
Yes, each arm is 14 mm thick and joined to the trunk along its whole elbow. Let the wax cool completely before you open the halves and they come out whole.
