Coffee ground knock box

I designed this to make handling coffee grounds a lot easier. You can knock the grounds directly into a standard coffee filter, which keeps cleanup simple and disposable. I also added a tray at the bottom so that if I want to rinse my espresso filter with water, I can do it right over the knock box—no stray grounds ending up in the plumbing.This model is compatible with regular coffee filters, making the whole process cleaner and more convenient.Print in PETG.
