You're working on automating your factory, but it would take a lot of time and resources to generate the required throughput for later levels, right? Well, yes and no.

The basic idea for this device is split into 2 parts:
- The storage system
- The clock

You must have all the "wires" items unlocked for this to work.
If you don't, come back when you have them.

* The left side filters' input is the signal from the hub, it will prevent any shapes that are not required from going into the storage system.
* The array of Belt Readers to the left of the input of the system are required in order to identify whether or not there's shapes arriving into the storage system.
* The array of Belt Readers next to the input of the system are required in order to identify whether or not there's shapes leaving the storage system.

The filters in the middle section are triggered by the clock, details in [The Clock] section.

Once the objective of the current level is complete, the hub will require a new shape, this will cause the filter to prevent any of the previous shapes from coming into the [Storage System].
Since no more shapes can come into the system, and all the remaining shapes will most likely have left the [Storage System] at this point, both Belt Reader arrays will return a 0 (no movement detected) to the clock, which will allow us to "flip" the clock by emptying it's storage.

Once the new shapes start arriving, the belt readers will send a signal to the clock which will instead tell it to start charging up again.

The clock works as a battery. You start charging it whenever the [Storage System] registers activity (the wire to the right), and discharge it once there's nothing going into or out from the [Storage System]

Once the battery is full, it'll send a signal to the [Storage System]'s filter array in the middle, which will allow shapes to be released from the storage system into the hub.


You can technically change the speed at which it charges, however due to the fact that a single storage unit can store 5K shapes, it provides more than enough time to store shapes in the main [Storage System].

Regardless of the amount of items your factories make, this solution should allow you to clear levels by brute forcing the final delivery.

Bonus Screenshots (should make it easier to build with respect to the hub)
2 storage systems for 2 fully automated shape factories, one per side of the hub. Each factory provides a single conveyor belt at full capacity once production ramps up. And everything is handled by a single clock.

Once the clock signals stuff to go in, I cut off any other shapes to prevent slow-downs and have only the required shape to go in.

Since my factories are too efficient, I had to slow down the rate at which the clock is filled, as I ran into an issue where the clock doesn't fully discharge before the next set of shapes makes it into the Storage Systems

Thanks for taking your time reading this guide, hopefully it'll help you level up your shape factories.
