Solid fill 3D PETG material
304 stainless steel pin
 
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.  Each arm is printed here in the backwoods of Mid-Michigan.  If you're looking to keep you cars cup holder in working shape but don't want to spend the extra for the aluminum version this is your option.  It includes the same geometry updates as the aluminum one allowing for better operation when opening and closing and we recently updated the item to use the same 304 stainless steel pin as the aluminum arms we offer.
 
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.
