Zanussi dishwasher wheel

Spare wheel for zanussi dishwasher (my model is ZDT 5052, but I believe that this wheel will fit most of zanussi models). Before making my own model I tried this one: http://www.thingiverse.com/thing:1755766
The "axis" part of this model looked exactly like original one, but when 3d printed it was very fragile, so I designed my own. My model is better suited for 3d printing - I've made it thicker and stronger than original and you can ptint it without support.
