I purchased for my 54mm Bambino Plus and have liked the quality and the looks of the Bulipu (yes, a "no-name" brand, although available at Amazon ~consistently for at least 2 years now) convertible portafilter--use it bottomless or with the included 2-spouts adapter, and at a price well below the Normcores and Cremas of the world (the price can vary over time--good to keep an eye on it). It even comes with a fine double-shot basket, not mentioned in the item listing, and may also come with a portafilter hanger. Available via Amazon/U.S. as well as other Amazon store locations. And the fit is fine, including with the stock Breville 54mm baskets.. I principally purchased it so as to be able to use a triple-shot basket in it, for a larger drink. It's been fine there fit-wise: my larger IMS triple-shot (18-22g) basket fits in the portafilter in "bottomless mode" with no issue; if I use it with the portafilter's spouts attachment, the attachment goes almost all the way in but not quite, but well past the point where it fits tightly into the portafilter and is no issue. And the stock Bambino baskets fit in the portafilter in either bottomless or spouted mode with no issue. https://www.amazon.com/Bottomless-Portafilter-Breville-Barista-Express/dp/B0CB5V22ZL
