Space Ring

This is an idea to make have less wiggling motion when BOSeTAMPER tamp the puck. The spacer fill the gap between your basket and flaps/ears of the portafilter to the BOSeTAMPER locking mechanism. 

Please check this video for more explanation and example

We are not including this on the commercial unit.
But here is the file if you want to download and print it yourself:

DK note:
IMHO we do not need this but use this so that I can make a neater video to share. Without the ring still tamp the puck and level. The key is actually get the correct depth setting, which base on your grind setting, your dose, your basket setting and your portafilter.
