Just printed one.
Will try it this week.

I am a bit confused. I was super excited to print this. But then could not find the filter files. Is there something I am missing?
@MindofBrad_400498 Thank you for letting me know. The filter file is a step file to be printed with no top or bottom walls. I see that I didn't upload a 3mf file for just the filters, I will upload one soon. I'll upload both a honeycomb set of filters and a typical mesh version.
Update 12 Nov 2024:
I have added a 3mf file that has both honeycomb filters and grid filters. The particle size is a bit more approximate for the grid style filters, however things may get stuck less often. (edited)
