Aeropress Inversion Collar

Using the inverted method with Aeropress can be tricky. This collar snaps onto the piston and supports the brew chamber during bloom, steep and flip. The holes make it easier to grip and remove the collar when you're ready to press. Anyone who wants but is unable to print one of these just send me a message and I will be happy to print and send you one for the cost of machine time, labor and postage. ($15 US, $20 international)

Update: you can also order it from shapeways here: http://www.s
