Update: I no longer use the Breville Bambino, but made a remix to make the portafilter wing holder and handle arm taller in an attempt to account for spouted portafilters! Not sure if this has enough clearance so please make measurements for your specific portafilter before printing. Thanks all!
Hi! I designed this a few months ago but wanted to use it for a little while before uploading. This has been tested for daily use on my own setup and accessories, and I could be missing something, so let me know if you run into any issues!
I specifically modeled this to be used for the Crema Coffee Products 54mm Bottomless Portafilter and the dosing cup that comes with the Niche Zero. I use both because I have a Breville Bambino, and also love myself a good pour over from time to time. I needed a holder that could do both. I've tried other designs before, but none of them gave me the option to put a portafilter or larger dosing cup easily under the grinder without unscrewing the adapter.
I have tried using this with 3 different sized portafilters, and it generally works well, but some sizing could be off, as this is primarily meant to be used for the Crema handle I posted above. I have also uploaded a version that has a shorter neck support for those who are using shorter portafilters like the included Breville Bambino portafilter.
I have also quickly designed a cover to block the screw head from being exposed, but I have not tested it.
NOTE: This has not been tested for spouted portafilters, just naked/bottomless ones, so I don't think there's enough clearance for most spouted portafilters.
NOTE 2: The alternative model has not been tested and is just a quick modification of the original design, so things might not be as flush and clean.
I used 30% infill with supports for the top tab holder (tree supports worked fine for me) with PLA, but PETG/ABS/ASA should work as well if you want to try dosing into a heated portafilter, but I have not tested with other filaments personally. Whatever you choose will surely mesh better than the Bambu Green PLA I had lying around!
