Adjustable drink can dispenser

Thanks to Enigma you for her work and sharing.

Following a request from Everspace I just added adjustable parts for these typical American-style cans :

- 120 mm Energy Drink Can
- 86 mm Regular Soda
- 68 mm "Mini" Soda

Thanks to Pulsar Nova for giving me the exact size of Monster and Guinness cans

- 124 mm Guinness Can

- 131 mm Monster Can
