The 3D printed passenger side cup holder replacement arm is printed using PETG which is about the same type of material as plastic pop bottles and printed solid fill for the most stregth possible.  The geometry has been revised to help this arm work without binding like the oem arms often did.  If you are looking for an aluminum one we have those as well listed here on ebay.

Replacement arm only.  To be used with your existing assembly.

NOTE:    This color is Galaxy Black which is a matte black with a bit of silver metal flake present.  It does not match the factory gloss black like the aluminum arm does.  Color is exactly as pictured.
 
Fits both Sky and Solstice
