8mm nut Spinner

thingiverse

Nut spinner for 8mm nuts, with a 15mm inside diameter. This design is based on an excellent concept by "boopido". The device has a hole that allows a bolt to pass through it, making it suitable for longer bolts. It's not intended for long-term use, so there's a small chamfer to guide it onto the nut. Simply spin it tight and you're good to go - it can even fit in your pocket! I personally use this spinner to secure my vertical kayak posts, as it reduces the risk of scratching the car roof and prevents rotting in the kayak bag.
