This screw tree is designed to collect screws when taking apart electronics. The wood is slightly taller (22mm inside) to hold a suitable amount of them. The rounded edge inside is there to make it easier to get the screws out. At the bottom of the tree there are magnets and rubber feet.
The large space in the tree is without a magnet.
