Instructables user iminthebathroom converted an old Bunn coffee maker into a coffee-making R2 unit that he calls "R2-D2: Dark Roast Edition."
Thanks to an array of custom brass and copper parts, the retired Astromech has been given a second life as a caffeine dispenser. Even in a time of galactic peace, Artoo is always willing to do his part.
If you want your own R2-D2 coffee machine, you can put one together using iminthebathroom's helpful step-by-step instructions.
