◆ Plaster
Cast your own 140 mm Venus de Milo in plaster or concrete, from a public-domain museum scan.
The Venus de Milo, from her plinth to her hair, as a 140 mm statue for a shelf, a desk or the garden. The drapery, the twist of the body and the famous missing arms all come through, and she stands on her own plinth.
The master is a 3D scan of the plaster cast of the Venus de Milo in the Royal Cast Collection of SMK, the National Gallery of Denmark, published by SMK as public domain. It is cast in a flexible silicone mold made with the hugging-shell mode of our silicone mold maker, which the site's own mold advisor picks for her: the drapery folds would lock any rigid two-part mold, and silicone peels out of them.
Plaster or Jesmonite gives a crisp white statue for a bookshelf; a fine concrete gives a heavier one for the garden or a doorstep. The same mold also takes resin, soap or candle wax.
Print the base with the statue fused onto it, the two shell halves and the six clamps, pour about 127 ml of silicone, and cast in the silicone that comes out. The zip carries every printed part, the Venus 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 parts pulled apart around the master, not a photo.

Print the base, which has the master already fused onto it, the two shell halves and the six clamps (all six are in clamps.stl). No supports.
Stand the shell halves on the base around the master and push the six printed clamps over the seams. Steel binder clips work too, the seats for them are built into the shell.
Tape the outside seams or run a bead of hot glue along them, because silicone finds every gap.
Mix 148 ml of silicone in one batch, pour it into the open top in a thin stream, and fill level with the rim.
Once it has cured, unclip the shell, lift it off and peel the silicone off the master. That silicone is your mold.
Set the silicone back in the shell to keep its shape, and cast into it through the opening the base left.

Casting plaster is the easiest and gives the crispest white finish, ready to demold in about an hour. Jesmonite is stronger and chips less, which suits a slim figure like this. For outdoors use a fine concrete without gravel and leave it a day before demolding.
Brush a thin first coat into the mold with a soft brush so it gets into every fold, then fill the rest. Tap the mold on the table for a minute and the bubbles rise out.
Yes, the mold takes pillar wax. At about 45 mm across she burns unevenly, so it works best as a decor candle you do not light for long.
