A round tealight holder 78 mm across and 44 mm tall, with 28 rounded vertical flutes, a slight draft and a recess on top that takes a standard 38 mm tealight.
Made with the box mode of our silicone mold maker in its round shape: print the base with the holder fused onto it face up, the walls and the clamps, pour about 389 ml of silicone, and the block you get casts the holder upside down, recess and all. Fill it with concrete, Jesmonite or plaster.
The zip carries every printed part, the holder 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.
What you need
- About 423 ml of silicone (mix it in one batch)
- Concrete, Jesmonite or plaster: each cast is 162 ml
- Tape or a hot glue gun for the wall seams
- Fine sandpaper and felt pads for the finished holder
How to cast it
- Print the base with the master fused onto it, the two walls and the two clamps.
- Stand the walls on the base, slide the clamps over the corners, and seal the outside seams with tape or hot glue.
- Mix 423 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 and walls off and pull the silicone block off the master. That block is your mold.
- Turn the block over: the opening is the bottom of the holder. Fill it with a fine concrete mix, tap the sides for a minute to raise the air, strike the bottom flat and leave it to cure.
- Demold after a day, sand the bottom flat and stick on felt pads so it does not scratch the table.
