Concrete incense holder disc mold, 2 styles
Two 90 mm concrete incense holder discs, one plain and one with a gear edge, each with a raised stick holder, cast in one printed tray.
◆ Concrete
Two 90 mm concrete incense holder discs, one plain and one with a gear edge, each with a raised stick holder, cast in one printed tray.
A printed tray for a pair of concrete incense holders, 90 mm across: a plain round disc and one with a 16-tooth gear edge. Each is a 10 mm disc with a 4 mm lip round its rim that catches the ash, and in the middle a raised boss 18 mm across and 8 mm proud with a hole for an incense stick, 2.6 mm across at the top and 9 mm deep, so the stick leans a little toward the rim. The pair takes 147 ml, about 323 g in concrete.
Made with our tray mold generator in its rigid tray mode: print the tray, wipe in release and pour, no silicone. The discs are cast upside down: the boss, the stick hole and the lip come off the smooth tray floor, and the backs are the side you strike flat. The tray is about 200 x 100 mm.
Cast them in grey, black or terrazzo, or in white Jesmonite with a gold rim. A cone of incense sits on the boss as well as a stick in it. The zip carries the tray exactly as the tool exported it, the two discs on their own as an STL, the master uploaded to the tool, and a print and pour sheet.
Shown as a 3D render of the printed tray with the concrete incense discs in front, not a photo.
Print the tray as exported, cavities up, no supports. PLA is fine.
Wipe a thin film of mold release or cooking oil into every cavity, including the grooves.
Mix a fine concrete or Jesmonite to a thick pour, fill each cavity, and vibrate it out: tap the tray on the table or hold a sander against the side for a minute until no more bubbles rise.
Cover the tray and let it cure for 24 hours, then flex the tray and tip the pieces out. Sand the back flat, and seal them once they have dried for a few days.
Push an incense stick into each hole while the discs are still a day old and soft to check the fit; a 2.5 mm drill bit by hand opens a hole that cured too tight.

Standard bamboo-core sticks, about 1.5 to 2 mm across at the base, which covers most Indian and many Japanese sticks. The hole is 2.6 mm at the top and 2 mm at the bottom, 9 mm deep. For thinner coreless Japanese sticks, push a little sand or salt into the hole first.
Yes, set the cone on the flat top of the boss, or on the dish of the disc, and the 4 mm lip keeps the ash in. A backflow cone needs a holder with a channel, which this disc is not.
Yes: concrete and Jesmonite do not burn, and a stick or cone only warms the surface. Seal the disc so ash wipes off, stand it on a heat-safe surface, and never leave burning incense alone. Do not cast it in resin, which can scorch under a cone.
