This is a resized lower body component for the spirographic WDT tool, making the tool compatible with the portafilter on the Cafelat Robot.
You need to print all components from the original design, except the lower body, and follow the assembly instructions there.
I also used the longest needles I could find, to reach the bottom of the portafilter. I used these, but others are available.
The author remixed this model.
Adjusted dimensions of lower body to fit Cafelat Robot
