Smartstore mini storage (for magnetized minis)

Two floor mini storage for the Smartstore.se 34x25x16 cm storage boxes. The lower floor is about 63 mm in height and the top one 60 mm. Those boxes are sold by Jumbo and Coop in Switzerland.

You need:

• 8x 10 - 40 mm long M3 screws with cylindrical heads
• 8x M3 nut
• 2x Some magnetic floor material with 185 x 250 mm (the slot for it is 2 mm in height)

My hardware store sells 250 x 500 mm “Streckmetallblech Stahl roh” (translates to "expanded metal sheet") which works perfectly for this.
