Aeropress Cup Adapter

I bought a 10 oz Yeti Rambler tumbler only to find out the Aeropress + flow control cap doesn't quite fit properly. The AP funnel is just too big, especially for travel. So I designed my own low profile adapter.

I first created it in Tinkercad and then created a parametric OpenSCAD version.

For the 10 oz Yeti to AP + Flow Control Cap, use the following settings:

// Cylinder wall thickness
$WALL_THICKNESS = 4;

// Aeropress outer diameter
$AP_OD = 68;

// Aeropress cylinder height
$AP_H = 4;

// Flange outder diameter
$FLANGE_OD = 76;

// Flange height
$FLANGE_H = 2;

// Cup inner diameter
$CUP_ID = 58;

// Cup cylinder height
$CUP_H = 4;

I would recommend using PETG or ABS/ASA.
