n-m vending machine - JE 1.21

3D Model

Built this vending machine for a friend from an SMP. Pay with n items, get m items in return!

Some characteristics: * Bottom half sets the $price (#items + 1), top half sets the $output (#items + 3). * Of the two stacked barrels in the front, payments go in the bottom one, output goes to the top one. * The machine does take multiple payments, but doesn’t return partial payments. * Only works with stackables, except for filtering the payments. Best option is to keep the price between 5 and 63 items, to make sure your customers don’t break the machine with other items (unless it doesn’t matter what stackable item they pay with). * Bottom dropper should be completely full. * Also there might be a reliability issue for very low (<5 items) or very high (~5 stacks) amounts, but other than that this works like a charm. * The signs are NOT essential. * Might need some alterations to work in Bedrock as well.

**Disclaimer: This machine isn’t completely my design, but I forgot what I based it on.
