Okay, thats a bit weird, but it works!
This cup has the same diameter, 67mm, like a normal coke can (0,33l and 0,5l).
I made this cup for an vendor machine, so i can sell other things instead of drinks.
Cigarettes as examples, a normal box with 20 sticks will fit inside plus an lighter or so.
I reduced the highness of this cup, so that a box will fit perfect. so the cup is 92mm high, but an original can 115mm. Depending on the construction of the vendor machine, you could need the full high of the can.
