About this 3D model

51mm Tamper (resize to your portafilter) and knock box. The bottom of the knock box has an inset to add a piece of rubber cushioning so its not as loud when knocking your grounds out. This set was made to be used in tandem with my Ball brand mason jar coffee holder and scoop set found here https://www.myminifactory.com/object/3d-print-cwcdesigns-coffee-scoop-scoop-holder-and-funnel-for-mason-jar-68647
