I modified the inner bin by creating four 1 inch (25.4mm) recesses that are 1mm deep on the underside of the base which are sized to fit the Gorilla brand 1 inch diameter adhesive rubber pads.  I used standard supports (not tree), along with Bambu Lab Support for PLA. That way, your final print will have a nice, clean separation of the support discs, leaving a smooth, flat surface to stick the rubber pads to. The pads will fit snugly, and the 1mm deep recess allows just enough of a lip to secure the rubber pads in place so they won&#39;t slide around. NB  Bambu Studio will generate a pop-up window asking to change a couple of settings when it detects you&#39;re using Support for PLA filament… ignore that request, as the support material will work better and separate far more cleanly without the modifications being suggested.  Once printed, pop out the four 1mm thick discs from the underside, stick on the four Gorilla 1&#34; diameter rubber pads, and you&#39;ll have two immediate benefits. The first is a non-slip base, and the second is that it will also provide a little more sound dampening when you&#39;re knocking your portafilter to release the coffee ground puck. Lastly, if you&#39;re looking to be environmentally friendly, you can acquire compostable waste bags from sources like Amazon. What you want to get are the ones that are listed as 1.2 gallon (5~6 liter) size, and they come in either clear or translucent green colours. Since those bags are made from corn (just like PLA), they&#39;re fully compostable in either your own yard compost, or your municipal collection system (if one exists in your region). Even if you can&#39;t compost them, it&#39;s still a better option for the landfill.
