Mold settings
Outer shape of the die + piston. Auto picks round or rectangular from your model's footprint. The cavity always follows your uploaded model either way.
60 mm
Size of the finished piece. Your model is scaled to fit this.
2.5 mm
Printed wall of the die + piston. PETG holds up best over many presses.
Press mold
Print the die and piston (PETG recommended — holds up well against damp clay and bath-bomb mix,
which is mildly acidic when wet). Pack your material firmly into the die, press the piston down
until the cap seats on the rim, trapped air escapes through the vent, then lift the piston and
release the finished piece.
