Description
This is a cup designed to replace 4-inch filter socks in a sump. I'm using two of these, printed in PLA, on a Waterbox 75.2 tank. I run filter floss in them generally, but they also work with media bags for carbon/gfo/other media.
I printed it in two parts, and used CA glue to join the rim with the body.
