AeroBox - World AeroPress Championship (no light)

⚠️ IMPORTANT — SCALE SIZE LIMIT (READ FIRST)

This AeroBox version only works with scales up to 153 mm × 131 mm × 27 mm (e.g. Timemore Basic / Basic 2). If your scale is larger, this version won’t fit / won’t work properly.

AeroBox — Measure Your AeroPress Press (Grams Out + Flow Rate)

AeroBox is a 3D-printable AeroPress press stand that helps you control the press phase with numbers, not guesswork.

Most recipes say things like “press gently” and “stop at the hiss.” AeroBox + a compatible scale lets you press with two clear targets:

• Grams out = how many grams of brewed coffee you actually press into the cup
• Flow rate (g/s) = how fast those grams come out while you press

This makes it much easier to repeat brews—especially if you like stopping the press before the hiss for a cleaner cup.

Competition context

This is the first prototype used by Jan Ahrend (Switzerland) at the 2025 World AeroPress Championship (WAC), earning 2nd place.

Quick start (beginner-friendly)

1. Put your cup on the scale and tare it
2. Place AeroBox over/around the scale + cup
3. Set your AeroPress on AeroBox

4. Press while watching the scale:

    

   • stop at your target grams out
   • keep a steady flow rate (g/s) if your scale shows it

    

Printing notes

• PLA is tough enough
• Needs to be printed with supports
• Minimum of 10% infill and 2 top/bottom layers (ideally 3 layers)
