Espresso Grounds Distributor - 58mm

This is a coffee distributor I put together for my 58mm gaggia classic machine (using a La Marzocco Precision 14g Portafilter for what it's worth), and this could probably be quite a bit shorter to fit this to be honest as it's screwed in almost entirely for my current usage.

Perhaps the surface could be improved by making a design that is more easily sanded (like the single edge I've seen on some commercial units) as I don't believe threaded abs parts can be acetone-vapor smoothed, but I wanted to play with the spinning-based functions in Fusion360 a bit more so this is what I made. Feel free to CFD this spinning in a partially packed bed of coffee grinds for optimal coffee smoothing if you're real bored.

I also used fusion's thread function to make this, and removed 10 or maybe it was 100 microns to allow the threading to slide smoothly, but I think creating a custom thread using the spiral tool would allow reduced overhangs for printing and allow tapers on the ends for bett
