Octo Mochi Fidget Spinner

A mochi octopus that curls up to rest and flings its arms straight when you spin it.

At rest, curled up. Eight arms of five hinged links each fold in around the mochi head.

Pinch the grey pads. They hold the steel 608 bearing at the centre and stay still in your fingers.

Flick the head. Head, ring and arms turn together around the bearing, and the links start to swing out.

Spinning, arms straight. The curl is gone: 3.6 in across becomes 4.1 in.

Slowing down. As the spin fades, the arms fold back into a curl.

Curled up again. Ready for the next flick.

A small octopus for busy fingers

It is a fidget spinner shaped like a mochi octopus: a white dome head with a smiling face, an orange ring, and eight arms of hinged orange and white links.

Pinch the two grey pads between thumb and finger and flick the head. Head, ring and arms spin around a steel 608 bearing while the pads stay still.

It is for a desk, a long call or a quiet minute: something to turn in your fingers while you think, and a cheerful face to look at when you stop.

Curled at rest, straight in a spin

Each arm is 5 links joined on pins, so it can bend at every joint. Spin the head and the links swing outward until the arm reaches straight. Let it slow down and they fold back into a curl.

Drag the slider to speed it up and watch the arms reach out.

Good to know

Does it need batteries?

No. There is no motor and nothing to charge. A flick of your finger is what spins it.

How do I spin it?

Hold it by the two grey pads, thumb on top and finger underneath, and flick the white head or an arm sideways. The pads stay still while everything else turns.

Why do the arms straighten when it spins?

Each arm is a chain of 5 links on pins. When the head turns, the links swing outward and the arm reaches straight. When it slows, they fold back into a curl.

How big is it?

About 3.6 in across with the arms curled, 4.1 in across with them straight, and 1.3 in tall. It weighs about 1.1 oz.

What is it made of?

PLA plastic in white, orange, black and grey, turning on a steel 608 bearing, which is included.
