Step-by-Step Build Guide

​

Step 1 — Build the Floor

Place a 3×11 quartz block floor. This is 3 rows wide and 11 blocks long.

​

Step 2 — Add Side Rails

Place a quartz block on each side (left and right long edges) to prevent the player from falling off the machine while using it.

​

Step 3 — Place Hoppers Behind Brewing Stands

Place temporary blocks along the further long edge of the floor (where the brewing stands will go). Then place 11 hoppers behind these temporary blocks, sneaking and clicking on the temp blocks so the hoppers connect to them (face toward the brewing stand row).

​

Step 4 — Place Brewing Stands

Remove the temporary blocks and place 11 brewing stands in their place, on top of the quartz floor. The hoppers from the previous step should now feed into the brewing stands.

​

Step 5 — Place Chests

Place double chests and trapped double chests alternating next to each other on top of the hoppers — normal chest, then trapped chest, then normal chest, then trapped chest, and so on. Alternating between regular and trapped chests allows them to be placed side by side without merging.

​

Step 6 — Place First Row of Hoppers

Place 1 row of 11 hoppers directly on top of the chests. These hoppers face down into the chests.

​

Step 7 — Place Circular Hopper Rows

Place 2 rows of hoppers on top of the previous row in a circular pattern. This creates a loop so items flow in a circle, putting water bottles across all chests below.

​

Step 8 — Build Walls

Build a 1-block-high quartz wall around the top hopper area — front, back, and both sides.

​

Step 9 — Fill with Water

Use the Magical Water Bucket to fill the enclosed area with water. This is where you’ll stand when using the Bottle Filler macro to fill water bottles.
