This is a mechanical fidget spinner with a unique twist: when spun, the armored plates fan outward, then snap back into place as the spinner slows. You can also slide your finger across the spinning plates to close it manually — it's as satisfying as it sounds.
✅ IMPORTANT NOTES – READ BEFORE PRINTING
I want you to have success as much as you do. so please reach out with any questions or issues, I'll respond fast.
This model requires bearings and magnets to function as designed. If you skip these parts, it will not work properly.
You also must:
Clean your bed surface (brims help, but a dirty bed = failed prints)
Use decent filament (brittle or cheap stuff = broken parts)
To address variation between magnet strength there are two versions. One for weaker magnets and one for stronger magnets.
The Amazon Link Contains weaker magnets while Bambu lab sells stronger magnets
🔧 Required Parts
12x 6×2 mm Magnets Buy on Amazon - Use Weak Magnet Version
1x 608 Ball Bearing (spinner-grade recommended) Buy on Amazon
Glue (for securing magnets)
(Optional) Lubricant (to reduce break-in time)
🎨 Filament Recommendations
Material
Performance Summary
PLA Basic
Strong, smooth, breaks in quickly, highly recommended
PLA Matte
Strong, grippier, longer break-in time, works great once loosened
PLA Silk
Looks and works great, but brittle — use only if you don’t plan to drop it
PETG
Strong, longer break-in time, works great once loosened
🖨️ Printing Instructions
Prints in 3 pieces:
Main Body
Handle Plug
Handle Socket
Designed for 0.12mm layer height with a 0.4mm nozzle
Print time is approximately 3 hours
Brim points are added to help bed adhesion
Remove if your bed adhesion is reliable
Clean your bed before printing — this helps more than any brim
🧩 Assembly Instructions
(Refer to the assembly video below for visuals)
Prepare the Parts
Remove all brim points from the main body and handles
Look at the print preview to see where they are, they may not be obvious.
You may want to use tweezers to help.
Wiggle the armor plates to loosen them — they should move freely.
Install Magnets
Each armor segment has two small flaps that opens with 2 magnet cutouts — follow these steps carefully:
Open the Outside flap on a segment to expose the magnet pocket inside.
Insert one magnet into the hole on the inside/center — this becomes your inner magnet.
Stack two additional magnets on top of that one — these are temporary spacers.
Close the flap — one of the spacer magnets will slide into the outer magnet hole on the body.
Remove the top (unused) spacer magnet.
✅ You’ll now have two magnets perfectly aligned — one inside the flap, one in the body.
⚠️ Make sure the magnet polarity is correct and pulls the plates shut!
Install Bearing
Push the 608 bearing into the center of the spinner body.
Assemble Handle
Push the “plug” side of the handle through the center of the bearing.
Snap the “socket” side onto the plug, aligning the hex cutout.
🔧 Break-In & Tuning
Depending on the filament, some hinges may be stiff at first — gently work them loose.
Break-in time varies by material:
PLA Basic: quick
PLA Matte: slower
PLA Silk: fast but fragile
Add lubricant for smoother action and faster break-in.
Continue to use the spinner to break it in.
The goal is to get all hinges to open and close automatically.
