Eight Christmas tree wax melts with garlands and baubles, poured straight into a printed tray. No silicone.
A printed tray for eight Christmas tree wax melts, each 34 x 47 mm and 12 mm deep: three tiers, a star on top and a short trunk, with two garlands swagged across the tree and five little baubles standing proud of the face. About 8 ml of wax each.
Made with our tray mold generator in its rigid tray mode: print the tray in PETG and pour wax straight in, no silicone at all. The site's mold advisor rates a rigid mold a good fit for this shape (7% undercut against the best rigid seam, none against a straight pull), and every wall and garland is drafted, so the melts drop out once the tray has had a spell in the fridge.
Pour them in green with a pinch of gold mica, or in white for a snowy tree, and dust the garlands afterwards. The zip carries the tray exactly as the tool exported it, one melt on its own as an STL, the master uploaded to the tool, and a print and pour sheet with the volume of each cavity.
Shown as a 3D render of the printed tray with three green melts in front, not a photo.
Print the tray as exported, cavities up, no supports. Use PETG: wax goes in at 60 to 75 C and PLA starts to soften around 60 C.
Set the tray on a level surface. Melt the wax, stir in the fragrance at the temperature the supplier gives, and pour each cavity to the brim.
Let the wax set at room temperature, then put the tray in the fridge for 15 minutes: the wax shrinks off the walls.
Turn the tray over above a towel and press gently on the back of each cavity. The pieces drop out.

Because nothing on the tree faces back at the pour: the outline is drafted and the garlands and baubles are raised with sloped sides. Wax shrinks away from a rigid PETG tray in the fridge and drops out, so you skip the silicone entirely.
Let the wax set fully at room temperature, then give the tray 15 minutes in the fridge so the wax shrinks off the walls. Turn it over above a towel and press on the back of each cavity near the trunk first: the star is the thinnest part, so it should leave last.
Melt-and-pour soap, yes: spray the surface with rubbing alcohol, and freeze the tray for 15 minutes before you pop the trees out. Not chocolate: a printed tray is not food safe, and chocolate belongs in a food-safe silicone mold.
