AUTOMATED LABORATORY. (This is my first blueprint, so don't push me too hard)
36 Labs for all the potions. 12 Requester Chests, which only add 20 of each potions to the belt. As long as there are 20 potions of one color in the appointment, no more are dropped.
You can carry it with drones, and the belt won't get stuck. I use it because it's the best way to fit all the potions without creating a spaghetti of belts.
This is my first blueprint. I hope I did it well and that you enjoy it.
