Volvo P1800 Cupholder

thingiverse

Now that's what you were looking for. From 1967 Volvo introduced a new plastic part as a storage area between the two front seats of a Volvo P1800. They obviously forgot a cupholder in the design. Here it is. Print it, and stick it to the rear of the original plastic part with double sided tape. Fits exactly a European 330ml can. I don't really know if there are major differences in US-cans.
