Single Dice Mold Housing (with Keys)

If you are into making your own custom polyhedral dice, this minimalist 1-Dice Mold Square is designed to keep your silicone molds perfectly contained while saving both space and 3D-printing filament.

While there are many mold housings out there, this specific design features pre-made, built-in alignment keys (interlocking pins and sockets). This ensures that the two halves of your silicone mold snap together with 100% precision, preventing any shifting or offset lines on your final dice.

Print Settings & Recommendations

• Material: PLA or PETG works perfectly.
• Infill: 15–20% (Grid or Gyroid).
• Walls/Perimeters: 3 walls for optimal strength so the sides don't flex under the weight of the liquid silicone.
• Supports: No supports needed if your printer handles bridges well! The built-in pins/sockets are designed to print cleanly.
