EUREKA MIGNON HOPPER SLIDER SEALING
When the slider at the hopper is pulled out it leaves some small holes at the guide rail where coffee bean chips / dust can exit. To seal those openings I created a sealing ring which as well holds the slider in better position. The ring is printed with TPU (95) to better fit it to the hopper.
I printed with 0,16mm / 50% infill / 240°C extruder / 35°C textured plate temperature.
