wardrobe doubledoor slider

Our wardrobe has an double door, a sliding piece was missing.
So i desingned one (from the original) in Sketchup, repaired with Netfabb en printed it in PLA.
The wheel needs an 4mm pin.


I am new to 3d printing, so it was an good test for me and my printer ;)
It may need some adjustment, so the Sketchupfile is included.
Reactions are welcome.
