The Areopress (this thing) is a great little coffee maker, but sometimes the basket is a bit of a pain (literally) on the hands to remove after use, particularly if you like to apply a lot of pressure when brewing.

After a couple iterations, I got the fit loose enough to get on easily, but tight enough that it doesn't slip.

Notes:

• Printed in PETG, but PC or Nylon or ABS might be a better choice due to heat resistance. PLA probably not a great choice unless you use heat resistant PLA.
• Designed to fit the original Aeropress, but I think the Go model uses the same basket style, so I think it ought to fit.
• The parent model didn't fit for me, so I remodeled it to have better tolerances to be easy to get on/off the Aeropress without effort. This re-design roughly corresponds to a 2% size increase in the parent model (but simple scaling didn't work there either, because of the complex fit shape).

STEP file included in case people want to make their own adaptations.
