Improved Drums (7 sizes) for VEND

thingiverse

The original VEND drum hopper capacity was too large and when filled with Peanut M&Ms tended to stick and cut some of the candies when turning the drum. Cutting was even noticeable with smaller candies like M&Ms or Smarties. To prevent the cutting of the candies, I have incorporated a smooth off ramp which helps to gradually skim the excess candies off of the hopper when the drum is turned. I have also included 7 drums with 7 different hopper sizes. To allow users to experiment with different hopper sizes to see how much candy they can hold without having to print the entire drum, I have included test hoppers that match each of the 9 different drums. *Note: you don't need to print these to make the drum work but you will save a lot of material by testing first to make sure you are satisfied with the amount of candy the hopper can hold.

I did not use any supports when printing. When printing without supports, the upper wall of the hopper will not come out smooth (negligibly for smaller drums and noticeably in the larger drums), however this does not affect form or function of the drum.
