What AeroSweep is

AeroSweep is a prep tray that gives chaff and fines a better place to separate before the brew starts.

The workflow documentation is public and the standalone base tray plus optional insert remain under active testing.

Problem It Solves

Competition brewers often improvise chaff-removal and fines-handling in cramped containers or messy transfer steps. AeroSweep turns that prep stage into a more deliberate and repeatable tray workflow.

Variable It Controls

AeroSweep helps control pre-brew preparation state by making chaff removal and optional fines handling more repeatable.

How It Works

Ground coffee is spread onto a wider tray instead of staying in a narrow catch cup.
That wider geometry makes airflow-based chaff removal easier to perform consistently.
The optional ridged Fines Separator Insert sits inside the smooth base tray and can retain some fines during the same prep step.
The tray shape also makes the transfer into the brewer more deliberate than cramped cup-only handling.

When To Use It

When preparation cleanliness and transfer geometry matter during competition prep.
When you want a repeatable tray-based workflow for chaff removal before brewing.
When you want one workflow that can support optional fines trapping as well.

What It Does Not Solve

It does not guarantee a universally better cup.
It does not replace dialing in grind, water, or pressing.
It does not make every fines decision objective; the brewer still chooses the workflow endpoint.
It is less important if the prep stage is already clean, stable, and easy to repeat without extra tooling.
It does not replace good transfer habits if the brewer changes tray motion or airflow cues from brew to brew.

Print And Material Guidance

The PETG release profile uses a 0.4 mm nozzle and does not require supports. PLA is also suitable.
The smooth base tray measures 20.1 × 14.4 × 5.0 cm (7.91 × 5.67 × 1.97 in). The optional Fines Separator Insert measures 18.8 × 13.1 × 2.0 cm (7.40 × 5.16 × 0.79 in). There is no cap.
Print both parts at 100% scale and preserve the supplied orientation so the tray stays flat and the insert ridges remain open. The parts fit current Bambu Lab printers except the A1 mini.
For parts used around coffee, avoid a brass nozzle. Prefer a dedicated stainless-steel nozzle and PLA or PETG whose manufacturer documents food-contact suitability; the finished print still depends on printer cleanliness, surface finish, use, and cleaning.
Prefer a moist towel or gentle hand washing and let every part air-dry completely. AeroSweep is not dishwasher safe.

Version and status

Testing

Competition relevance

AeroSweep matters when the prep stage itself is a source of inconsistency and the brewer wants a more deliberate workflow before grounds reach the AeroPress.

Safety and trademark note

Brew Supply is independent and not affiliated with AeroPress or the World AeroPress Championship. Printed preparation tools should be handled with appropriate food-contact care and evaluated in your own brewing workflow.

Evidence boundary

Prototype work supports narrow handling and retention claims, not a universal claim of better flavor.

How to evaluate a Brew Supply control tool

Start with the workflow problem, not the promise of a better cup

A useful precision tool should make one decision or physical action easier to repeat. The first test is therefore operational: can you describe what changed, hold the surrounding recipe steady, and return to the same setup on the next brew? Taste still matters, but taste should be evaluated after the tool has demonstrated that it controls the narrower variable it claims to address.

Compare the normal workflow with the tool-assisted workflow using the same coffee, dose, water, grind, timing, and service target wherever possible. Record mistakes and setup time as well as successful brews. A tool that creates a cleaner measurement but adds too much friction may be valuable for structured testing and unnecessary for everyday brewing. That tradeoff is part of the result rather than something to hide.

Do not change several Brew Supply tools at once when the goal is to learn what one of them contributes. Add the smallest useful control, repeat the comparison, and keep an exit path back to the simpler method. This makes the product easier to judge honestly and prevents a complete competition setup from becoming more complicated than the recipe needs.

What the status means

AeroSweep is in active testing. Public documentation describes the current workflow and the claims Brew Supply is prepared to make, but testing status still means the design can change. Check the linked release hub and documentation for the current file, version, material notes, and limitations before printing or using it in a competition setup.

Open-source release discipline

Brew Supply separates an idea, a documented workflow, and a downloadable release. A landing page can exist before a file so the intended use and limitations are clear, but it must not turn a planned concept into an availability claim. When files are published, the download destination—not an old screenshot or copied model—is the authority for the current version. Feedback is most useful when it names the version, printer and material, fit, workflow conditions, observed failure, and whether the result could be repeated.

Before printing, check whether the linked hub actually contains the named product and whether its version matches the documentation you are reading. A profile link is a discovery destination, not proof that every concept or testing prototype on this site already has a downloadable file. Pages keep the unavailable state visible until a product-specific release destination exists.

Keep the original method available during testing. If a printed part does not fit, clean easily, survive the intended temperature, or make the workflow easier to explain, stop using it and record the failure before changing the model. Open-source iteration improves when unsuccessful conditions are documented as carefully as successful ones.

Competition legality is a separate check. Review the current event rules and confirm the exact printed version before adding any accessory to a competition kit.

FAQ

Is AeroSweep the same thing as a chaff tray?

AeroSweep covers that use case, but also accepts an optional Fines Separator Insert for partial fines handling.

Does AeroSweep replace BeanSieve?

No. BeanSieve is about whole-bean size composition before grinding. AeroSweep is about grounds handling after grinding and before brewing.
