Nesting ergo tamping stand for Pavoni & other 48mm portafilters

thingiverse

An ergo tamping stand for Pavoni & other 48mm portafilters. The stand features a gentle tilt forward towards the user in order to improve the ergonomics. It also features a rim along the front to capture any loose grounds, which can easily be swept out through the back. As an added feature when not in use, my dosing funnel nests on top via subtly matching contours, which in turn nests with my distribution tool. (https://www.thingiverse.com/thing:3027174) Many of the tamping stands I've seen seem to be excessively overbuilt. While I tamp with an unusually high amount of force, leaning my upper body into the tamper, I've found that one can remove quite a bit of material from the stand while still maintaining rigidity. So here I incorporate four strategically located carveouts; not only does it reduce the amount of material while maintaining more than adequate strength, it allows extra room for the odd protruding portafilter spout - my single spout does precisely that - and some added visibility... I also incorporated a rim around the front to contain any spilled grounds, which can be swept out through the rear of the tamping stand. Note that the front lip is kept minimal and is not meant to bear the weight of the tamp, but only to support the static weight of the portafilter and its handle. During tamping please direct the tamping force perpendicular to the portafilter's surface, which will direct the force slightly backwards (and matches the forward tilt of the stand). If you're not sure what angle this is, direct your tamp along the length of the front and back walls. This is how this tamping stand is meant to be used. As hard as I'm accustomed to tamping, I cannot feel the slightest bit of give or flexure with this stand. I printed it in PETG w/3.3 shells and a 27% infill. Of course YMMV... I designed and tested this tamping stand across several portafilters used in my Pavonis and La Cara, and should also work for an Olympia Cremina, though I did not test against the latter.
