Kia Cee'd (Ceed) Red Bull Can Holder

This is an ring-insert for the Hyundai 84699-3x000 Supplement C/Holder (which often comes in Kia Ceeds, as Hyundai owns Kia - see pictures). It shrinks the diameter of the supplement holder down to closely fit a Red Bull can or any other can with the same diameter. The can then cannot fall over even when accelerating or braking severely. The top of the insert has a somewhat steep fillet towards the center so placing the can inside - even when not looking while driving - is easier. Important note: Print this in PETG or something else that is quite temperature resistant. If your car is out in the sun you don't want the insert to melt down when it's printed in PLA.
