EMOTIONAL SUPPORT SOAP in raised letters on a 90 mm bar, as a silicone mold from printed parts.
A soap bar 90 x 62 mm and about 22 mm thick with a raised border and three lines of bold raised letters: EMOTIONAL SUPPORT SOAP, with SOAP set larger.
Made with the box mode of our silicone mold maker in its rectangular shape: print the base with the soap master fused onto it face up, the two walls and the clamps, pour about 337 ml of silicone, and the block you get casts the bar face down, so the lettering comes out on the show face and the back stays flat.
A joke bar that sells itself as a gift for a colleague, a new parent or anyone having a week. Pour it in a calm pastel with lavender or chamomile, or pour the letters a darker shade first so the words stand out. The zip carries every printed part, the soap 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 with the master fused onto it, the two walls and the two clamps.
Stand the base on the table. Set each wall down a few centimetres out from it and slide it in over the table until the ridge round the base sits in the groove at its foot, then slide the clamps down over the seams. Once they are on, the walls cannot lift, and the ridge seals the bottom.
Mix 369 ml of silicone in one batch and pour it into a corner, letting it rise around the master until it covers the top.
Once it has cured, take the clamps off, slide the walls straight out and pull the silicone block off the master. That block is your mold.
Turn the block over. Pour melt-and-pour soap at 55 to 60 C, spray the surface with alcohol to pop the bubbles, and let it set for a few hours.
Flex the silicone and push the bar out from the back. The letters read the right way round on the finished bar.

Pour the finished bar in one colour, let it set, then brush a little mica mixed with rubbing alcohol over the raised letters only, or rub a soap-safe colour into them and wipe the flat face clean.
This file has the text built in. For your own words, upload any bar with your text to our silicone mold maker, or make the lettering with the text sign designer first and use that as the master.
Calming ones: lavender, chamomile, vanilla or a soft cotton scent. It is a gift bar, so a gentle base and a mild fragrance keep it suitable for most people.
