Purpose
For those with 54mm (Breville/9Barista) or 55mm baskets (Izzo, ACS, Nurri) who want to grind into the cup and transfer to portafilter. Although the 55mm works with the Nurri, I found its baskets had a more rounded lip, so the Nurri version sits nicer on these.
58mm file also supplied - but it's only real use would be if you wanted to extend the cup closer to the funnel without dealing with the standard loose funnel.
Printing parameters
Printed in PLA+ at 0.20mm layer height on a 0.4mm nozzle.
I printed with supports with narrow side down the cup end is the more critical side, but I suspect it'll be fine either way.
It is designed to be a tight fit so it snaps on and stays on - but if your printer has less precision, LMK and I can put a looser fit up.
I only have 55mm baskets. 54mm and 58mm were predicted from that. Again, LMK if too tight for your baskets or have other sizes and I can put other versions up.
