The assembly instructions for the Medium Pump module have now been updated (https://www.softrobotics.io/flowio chapter 11) based on the latest enclosure designs. Notice that the battery is now placed underneath the pumps as opposed to behind them. Additionally, there is no longer a need to buy the Talon Ultra-Flex wire because I found an interesting way to make things work using the valve wires that we normally discard. Thus, it's a win-win situation because we can now save a couple of dollars per device while also reducing waste!
