Shimano Sora Chain guard (Y1NB98100)

What am I looking at?

Just a simple chain guard. I bought a new bike that had this piece missing for some reason.

Available files for download

I uploaded four different files:

• A .stl file, containing the model.
• Two .gcode files, both containing the model, one for PLA, the other for PTEG. You can print it using other material. That is your choice. 
• One .pdf with some technical data.

Where can spare parts be bought?

I do not know. I tried but I could not find any dealer that could get the piece. Anyway, the spare part code is Y1NB98100. You can check this here.
