Interlocking Knockbox for DeLonghi Dedica EC 685

thingiverse

This is an interlocking knockbox I designed to use with the DeLonghi Deduce EC685 portafilter. I got the basic idea from Boriskilk (see remixes) but figured theirs doesn't fit the Dedica properly - at least not my generation (don't know how often DeLonghi change these things). I also made it a bit taller with some added internal space for the ground coffee residue as I wanted to be able to knock out at least two double portions consecutively without having to walk over to the bin. With the measurements uploaded it should fit the DeLonghi 51mm portafilter just fine - the one in the photo was a tiny bit too tight in the interlocking section which led to a crack due to the pressure. This should fit snugly now... If not let me know! Might work with other portafilters of a similar size too. If so feel free to comment accordingly.
