This is a remix of the puzzle box by Scorch. The box was designed for a nickel and as it is very hard to find one in Europe, I've remodeled it to fit an Euro.

I've redesigned the holes and gaps, as it was a little too wobbly.

You need

1x M4x25mm screw (https://bit.ly/3F3V3jc)

1x M4 nut (Lock nut) (https://bit.ly/3voxc9I)

1x 7mm ball/pearl (http://bit.ly/3QF3MOn)
