Filter Sock Holder

I have a filter sock that filters the water at the outtake of my protein skimmer.  Currently, nothing holds it in place except a small tab located on the filter sock that slightly grips the outtake tube.  However, it tends to fall off once the sock fills up with water.  Therefore, I started shopping around for a filter sock holder, but couldn't find any locally.  I decided to create my own out of acrylic.

Now, when the filter sock fills up, it stays in place.  The water may spill over the sock but any debris that comes out of the outtake is captured in the sock.
