Solid knock box due to using a piece of 20mm electrical conduit covered with a flex, you could replace the electrical conduit with a printed tube 20mm diameter and 115mm long. This knock box has stood a year of abuse and still going strong.
I printed the box in ASA 15% infill but I think PET would also be OK
I used 95A flex for the tube but any flex that can soften the hit with a portafilter will be OK.
Conduit with Flex cover.
Conduit 115mm long
Conduit 20mm Diameter
I also glued some nonslip material to the bottom to make it stable on the bench
