The file 'BMW 1 Series Cup Holder 3D Printer Model' is (stl,step) file type, size is 304.9KB.
Here is a cup holder for older BMW 1 series that do not have a cup holder as standard. It fits over the door pocket. It is sized for take-away cups like Costa and golden arches, Coke cans, etc. The holder slots into the door hook as an interference fit so, depending on your printer accuracy you may find that it doesn't fit "perfectly".
I made mine in PET-G - you could use PLA but it may deform in a hot car.
I've attached the .STEP file if you want to customise it.
