Nice, another thing you could look for is egg crate think its listed as light diffuser but basically made of plastic and can easily cut and zip tie together and make a in tank media basket. Good luck with the project.
Does home depot sell acrylic sheets?
Id use a Dremel and make tiny slits in the acrylic just big enough for a small zip tie, thread it through and secure onto the egg crate and do it that way IMO.how would you cut and polish the edges of the acrylic...and then attach the egg crate...
