Nope, it's been a horrible failure thus far.
portafilter #1: 16 layers of aluminum screen let the water flush right through
filter 2: 3 layers of stippled aluminum tape popped
filter 3: two layers of aluminum can base with 23 ga. nail holes : water is still getting through kinda fast maybe like a 20 sec low pressure shot watery

I guess my nail holes are .63mm which is big on this chart.

Improvements to make
-add a water inlet so I don't have to flip the device to fill
-add a pressure gauge
-add gaskets to all inlets
-keep solving portafilter design
