I have these two parts on board as standard when I come to you. But you can also reorder them if you should lose them:

• The plate lifter
  With it you suck the aluminum plates and simply click them away from me.
  
  
• The opener:
  The magical magnetic tool you use to open my door.
  
  

Optionally available are these three parts:

• The height compensation feet:
  With them you bring me in perfect balance if you want to put your two- or three-stone next to each other instead of on top of each other.
  
  
• The construction kit:
  A mechanical-kinetic masterpiece. You'll need it if you want to build a two- or three-story marvel out of me.
  
  
• The footplate:
  You will need this if you want to equip your two-stone or three-stone with feet.
