Krups XP4030 espresso packing guide

thingiverse

This is a time-saving device for making espresso: instead of grinding coffee into a container, then pouring it into the brew basket, and doing multiple rounds of packing to prevent spillage, you can just twist-lock this onto the basket assembly, grind directly into it, and pack with no coffee wasted except for a little bit in the corners. It's designed specifically for my 10-year-old Krups XP4030, but will probably work with many other 52mm machines. My tamper is a little small (51.3mm diameter), so I made the bore 51.6mm in this model. This provides a nice fit when printed with Taulman t-glase - tight enough to keep the tamper square and pack coffee flat, but not so tight that it scrapes off any plastic bits. I believe t-glase is also FDA approved, which gives me confidence that no harm will come from using it. For non-FDA-rated materials or larger tampers, I recommend using the loose fit version, which is 52mm in diameter. You may see a little coffee getting past the tamper with this one, but it should still work well. I highly recommend unlocking the guide from the basket holder and removing it before you pull out the tamper. If you don't do this, you may create a vacuum that pulls the coffee back out of the basket. Print Settings: Printer Brand: MakerBot Printer: MakerBot Replicator 2 Rafts: No Supports: Yes Resolution: 0.1mm Infill: 30% Notes: I printed with Taulman t-glase black, extruder temperature at 250C (I think my hotend runs a little cooler than commanded), bed temperature at 45C, Kapton with PVA. Printing at 0.1mm resolution gave the curves a nice look, but 0.2mm would probably work just as well. It's best to print "upside down" with the locking features pointing upward. This reduces the amount of support needed and gives a smoother surface to mate with the brew basket, which means less coffee escapes.
