Industrial Reactor Gyro – Heavy Duty Fidget

Forget boring, smooth rings. This is the Heavy Duty Reactor Gyro. Engineered for those who want a fidget toy that looks like a piece of machinery from a Sci-Fi reactor, not just a toy.

Unlike fragile designs, this model features a geometric "Safe Zone" at the equator. This means the rings are mechanically locked in place and cannot fall out, no matter how fast you spin them.

🔥 Features:

• Heavy Duty Architecture: Deep industrial cuts and vents provide excellent grip and a strobe-like effect when spinning.
• Fail-Safe Design: A solid 3mm center band ensures the rings stay locked together.
• Print-in-Place: Prints fully assembled. No glue, no screws.
• Geometric Core: The center is a hybrid crystal/cylinder structure for a tech look.
• Keychain Ready: Integrated, sturdy loop.

🛠️ Print Settings (Important!):

• Supports: ⛔ NONE! (Do not use supports, they will fuse the rings).
• Layer Height: 0.2mm (Standard) or 0.16mm for smoother action.
• Infill: 20% - 40% (Grid or Gyroid recommended).
• Walls: 3 perimeters for strength.
• Material: PLA, PETG, or ABS.
• Brim: Avoid if possible. If you need adhesion, use a defined gap so it doesn't fuse the bottom layers.

⚠️ Post-Processing: The rings are printed with very tight tolerances.

1. Remove from the build plate.
2. Apply firm pressure to the center or twist the rings forcibly.
3. You will hear a loud "CRACK". This is normal and necessary to break the microscopic internal bridges!
4. Spin it for a few minutes to smooth out the rotation ("breaking in").
