SpinDot PRIME – Smooth Motion

New arrivals: 

SpinDot PRIME – Designed for Smooth, Controlled Rotation

SpinDot Prime is a precision‑engineered fidget sphere built around a very tight 0.3 mm clearance and a solid internal core. The design focuses on smoothness, stability, and clean mechanical behavior. To achieve the intended rotation quality, a few printing conditions are essential.

Filament Recommendations

• PLA Galaxy and standard PLA provide the most reliable smoothness and dimensional accuracy.
• PLA Silk can work, but spool‑to‑spool consistency varies. Some prints glide perfectly, others show slight over‑extrusion that affects the clearance.
• PLA Matt prints cleanly but introduces noticeably higher friction.

• All materials should be properly dried before printing.

   

Printer Setup

• A well‑calibrated printer is required (flow, Z‑offset, extrusion accuracy).
• 0.12 mm layer height produces the cleanest internal surfaces.
• The model uses manually designed supports for maximum reliability and clean removal. These supports ensure a perfectly round inner geometry without artifacts.

• Allow the print to cool completely before spinning. The internal core retains heat longer than the shell, and the mechanism only reaches its final tolerance once fully cooled (often longer than 30 minutes!).

   

Important Notes

• All parts are provided as separate objects.
• Do not use automatic arrangement or batch placement.
• Printing multiple units at once can break the support logic and reduce smoothness.

• For multicolor versions (Galaxy + White PLA), print one unit per plate to ensure clean filament transitions.

   

Available Versions

• Size M – single‑color
• Size M – dual‑color (Print time H2C: 3h, A1: 9.5h)
• Size L – single‑color
• Size L – dual‑color (Print time H2C: 6h, A1: 15h)

Each version is optimized for smooth rotation and clean support removal.

Result

With dry filament, a calibrated printer, and the included manual supports, SpinDot Prime delivers a smooth, controlled rotation that reflects the intention behind the design: precision through reduction.
