WTB 4" Filter Sock cover/blank

[TrottingReef]

I got a 4" Klir fleece filter roller. I have a Fiji Cube 24Advanced which has 2 4" filter socks. Klir makes covers for people with sumps with 2 socks but no one has any in stock anywhere. I can't use my Klir with out a way of capping the second filter sock hole. Anyone who does 3D printed parts want to try to make a cap to block the hole?

If you give me the actual dims of the hole I could laser cut one to file the hole with an oversized top to prevent it from falling through. I probably have scrap acrylic if you cover shipping

I gave up and just purchased a custom klir bracket to replace my sock bracket in my sump.
