I made my own. Steal eight neo magnets and a metal ruler. Then put them in stacks of two on one end of the ruler like this:

(+) (-)
(-) (+)

So the two beside each other should attract each other since one is positive and one is negative, and diagonally across should repel. Hold the magnets against the spider wrap and the latch should unfasten. If it doesn’t work try adjusting the magnets more so it lines up with where it clicks on the spider wrap.

How do I tell which side of the magnet is which side of the magnet is north, it's not marked.

If you have two sides that attract you can assume one is positive and one is negative. Put those beside each other. Then take the third set of magnets. Place it near the first two and watch it repel one of your first two magnets then place it diagonally from the one it repels, with the repelling side facing up. Then do the same for the fourth.

Top left should repel bottom right and top right should repel bottom left.

If you need more help you can look it up on YouTube :)

I’m not at home but there are videos on YouTube! That’s where I learned. Sorry I can’t be much of a bigger help!
