I really like this extension because you can take out the scale to use on the counter and the drip tray just rests on the sides of the base. It is a low profile drip tray, I need to drain it after each flush-brew-flush cycle.
I did print it in ABS. I don't know it PETG will hold the heat from a flush. The included picture is an early version of this one but dimension-wise it is similar.
The author marked this model as their own original creation.
