This is a multi part accessory holder for the most common Aeropress accessories.
It's designed to hold the paper filter holder, stirrer and scoop that come with the coffee maker, as well as one of the Able Fine Disk metal filters if you attach three copies of the finger STLs.
The wooden post holding the tool holder + finger attachment is common 3/8" diameter dowel, and was cut to 5" lengths. All parts were glued together using epoxy.
NOTE If you downloaded the original STLs without the _mm suffix, those files are in inch format and need to be scaled in your slicer. The new _mm files are in millimeter format so no scaling should be required.
