RL34 Refrigerator Inner Shelf Roller

Replacement Inner Shelf Rollers for Samsung RL34 type Refrigerator/Freezer. My first ever baby steps in 3D-Design. This is merely a test to get to know the workings of Thingiverse. The Wheel dimensions are NOT correct in the .stl. I did scale them in Cura before slicing, but did not bother to rework the .stl files itself!
Used FreeCad and Cura 4.
