A mesmerizing gyroscopic top that spins for minutes and then stays perfectly upright instead of falling over. A fun fidget toy, eye-catching desk piece, and neat physics demo all in one.
Ever wished your spinning top would keep its poise instead of flopping over? Gyro-Top Infinity is engineered so its center of gravity settles below the pivot, letting it self-balance inside its matching cradle. Give it a flick and watch it whirl; even if you poke it mid-spin, it stabilizes again. When it finally slows to a halt, it remains proudly upright—proof that good geometry beats gravity.
Key features
- Never-falls auto-stabilising design – fourteen N35 magnets arranged for balanced repulsion plus an M3 mild-steel bolt in the hub keep the top hovering, standing upright while spinning, and still perfectly upright after it stops—even if you tap it.
- Easy print: three separate files, minimum supports, PLA-friendly.
- Pocket size: 30 mm diameter top, 45 mm-square stand—carry it anywhere.
- Great for STEM: demonstrates gyroscopic precession and mass distribution in a hands-on way.
Magnet layout & polarity
You’ll need fourteen 6 × 3 mm N35 disc magnets in total: six in the top, eight in the stand.
- In the top
Press-fit six magnets into the hub, all with the same face (let’s call it “north”) pointing down toward the tip. Mark this face with a dot so you keep the orientation consistent. In the stand
Seat seven magnets around the outer circular pockets with their north faces pointing up.
Snap the eighth magnet into the centre recess in exactly the opposite orientation—its north face must also point down. When you drop it in, check that it repels one of the ring magnets; if it attracts, flip it over. you can add one more 6x1 mm disc magnet in middle of base to get more stability.One M3 mild-steel long bolt (15 mm) in the top
Before inserting the spindle stick, slide a single M3 mild-steel bolt (15mm long enough to reach the hub centre ) straight down the middle channel. This bolt is ferromagnetic, so it adds mass and gives the stand magnets a small “target” to lock onto when the spin slows. Tighten it just snug—no need for thread-locker.Because it’s ferromagnetic, this steel insert is attracted by the stand’s centre magnet and adds a bit of extra mass at the tip, sharpening balance and giving a satisfying snap-to-centre when the spin slows.
With every stand magnets presenting the same pole upward, the whole stand repels the six hub magnets in the top. That uniform repulsion is what lets the spinner hover, stay centred, and remain upright even after the spin winds down.
Lower the top slowly onto the cradle and you’ll feel a gentle bounce as like poles meet; give it a flick and enjoy the never-falls-over effect. If the top drifts off-centre, one stand magnet is likely upside-down—flip it and the balance returns.
