58mm Bottomless Portafilter Tamping Station

58mm Bottomless Portafilter Tamping Station

I designed this specifically for the following Breville compatible bottomless portafilter, purchased from Ali express: Coffee Bottomless Naked Portafilter 58MM Coffee Machine Filter Holder Espresso Handle Soild Wood For Breville BES920/980/990

This is likely not universal but it's all I have to test with. 

The distance between the portafilters outer edge to the handle collar is just shy of 20mm which fits snugly in the tamper station with minimal movement.

The cylindrical storage compartments are optional to save a little on print time and material if not desired.

I used the following 19mm x 2.2mm self-adhesive PVC bumper pads from Madico on the underside at each corner to prevent sliding and protect my work surface which seem to work well for me: Madico 19mm Round PVC bumper Pads.
