A net is a 2D unfolded pattern that, when cut out and folded along indicated lines, forms a 3D shape. For a cube (dice), the net is a cross-shaped arrangement of 6 connected squares. For a cone, the net consists of a circular sector (the curved side) and a circle (the base). Nets are the foundation of papercraft and geometric modeling.

Download the PNG, print it on thick cardstock (200gsm or more). Cut along solid outer lines. Use a ruler and a blunt tool (like a dried-out pen or scoring tool) to pre-crease the dashed fold lines. Fold inward, apply glue to the gray tabs, and press firmly until dry. For best results, use white glue or a glue stick applied sparingly.

Solid lines are cutting lines — you cut along these with scissors or a craft knife. Dashed lines are fold lines — you fold the paper along these (usually inward for a clean finished look). The gray-shaded flaps are glue tabs where adhesive is applied to join faces together.

The cone's side unfolds into a circular sector. The sector's radius equals the slant height (l = √(r² + h²)), and its arc length equals the base circumference (2πr). The sector angle is θ = 360° × (r / l). The base is a separate circle of radius r, with small tabs to attach it to the curved side. All calculations update live as you adjust the sliders.

Yes! Switch the Face Style to "Custom Text / Emoji" and type any short text, symbol, or emoji into each of the 6 face fields. You can create story dice, decision dice, alphabet dice, or themed game dice. The text automatically scales to fit each face.

The estimated print area is shown below the download button. Most standard dice nets (20–35mm face size) fit comfortably on A4 or Letter paper. For larger dice or cones, you may need A3 or tabloid paper, or you can scale the downloaded PNG in your printer settings. Always check "Actual Size" or "100% Scale" in your print dialog to avoid unintended scaling.

This usually happens when your printer applies automatic scaling. In your print dialog, look for options like "Scale: 100%" or "Actual Size" and disable any "Fit to Page" setting. The downloaded PNG has the correct pixel dimensions corresponding to your chosen millimeter sizes at 96 DPI screen resolution. For precision-critical projects, verify with a ruler after printing.
