There is a new version which fixes several issues, check it out here: https://www.printables.com/model/892372-gaggia-classic-short-extra-long-drip-tray-v2
I wanted a longer (length wise) drip try for my gaggia classic pro so I could flush the steam wand into it. Also, I wanted it to be short (height wise). This model is fully 3d printable, without supports.
You'll need to print this out of PETG, ABS, or ASA. If you use PLA it'll warp from the heat - and it'll leak. I used 4 walls, top, and bottom layers - which should be enough to make this water tight. I printed with 25% line infill - but anything similar should work fine.
Because this is such a large model, I recommend printing with a brim, in an enclosed printer, or it'll warp.
Also, this ‘should’ work with the gaggiuino scales found here, but I've not tested it yet.
The author marked this model as their own original creation.
