If you want to build a cube you will also need the extruder disc for the square, this contains only the rectangle.
The longer sides of this rectangle have the same length as the square.
 
You will receive extruder discs made of PLA to make the motif shown from soap dough (or clay, polymer clay or other modeling pastes).
Please choose the suitable disc size for your extruder.
Not all motifs are available in 18mm, as the motif becomes too delicate and cannot be extruded well.
PLA is a plastic made from corn flour that is stable up to 65 degrees Celsius.
Too high temperatures and too much contact with water can damage it, so wash the extruder disks with lukewarm water and a sponge or brush; they are not dishwasher-safe.
