SpinDot DICE – Modular D6 System

New arrivals: 

SpinDot DICE – Modular D6 System

A new way to dice — under 30 minutes. A print‑in‑place D6 with a freely spinning core.

SpinDot DICE is a completely new take on the classic D6: a print‑in‑place dice with a freely spinning internal core, revealed through engineered slits. Two cages, three cores — four modular combinations. Plus a Fast‑Print Edition, a clean two‑color version with high‑contrast pips - and a premium version with full color changes (recommended for H2D/C makers).

How SpinDot DICE actually rolls

SpinDot DICE isn’t just a dice you drop — you roll it across the table. As the cage moves, the internal core begins to spin freely, creating a unique double‑roll effect: the outer dice rolls normally, while the inner core rotates independently.

This motion is what makes SpinDot DICE feel alive — a dice with its own internal momentum.

Special Thanks

A huge shoutout to @bsfoster0 for the original idea behind a rotating core dice! I was fascinated by the concept and wanted to bring it to life. I have completely engineered every part from scratch to ensure a perfect print-in-place experience, signature SpinDot haptics, and ultra-fast print speeds. A big thank you to @bsfoster0  for the spark that led to this modular system!

Included Variants

Cages:

• Round Cage – Smooth Geometry A rounded, soft‑edged cage with openings on all six faces. Rolls better, feels more natural, and is ideal as the default version.
• Square Cage – Angular Geometry A sharper, more geometric cage with the same six‑face openings. More technical, more defined edges, and visually striking.

Cores:

• Round Core – smooth and balanced A clean, rounded internal sphere with soft geometry. Rolls smoothly and gives the most natural motion feel.

• Twist Core – dynamic and expressive A twisted internal geometry that creates shifting reflections and more visible motion.

   

   

Features

• Print‑in‑place spinning core: Breaks free as soon as you move the dice after printing.
• Lightweight & Efficient: Only approx. 5.5g of filament per dice (single color).
• Four modular combinations: Any cage works with any core.
• No supports required: Fully optimized for clean bridging and smooth rotation.
• Designed for silk filaments: silk filaments create deep reflections and make the motion highly visible.

• Readable, high‑contrast pip design: Ideal for display and actual dice use.

   

Print Time

• Standard Edition (0.16 mm): 30 - 40 minutes
• Fast‑Print Edition (0.20 mm): <20 minutes
• Dual Color (0.16 mm): 3:10h (H2D/C) - 5:45h (A1)
• Premium Version (0.16 mm): 3:10h (H2D/C) - 8:40h (A1)

• No supports, no assembly

   

Recommended Print Settings

• Layer height: 0.16–0.20 mm
• Material: Silk PLA, Galaxy PLA, or smooth PLA
• No supports
• Slow outer walls for best surface quality

• For modular prints: print pips separately in white or another high‑contrast color

   

No assembly required!
