3/4" PVC Pipe and Egg Crate

A very easy way to create a rack is to cut 4 pieces of 3/4" PVC in equal lengths. Take a hack saw and cut 2 straight lines into one end and secure it to the egg crate.

This type of rack will create a non-void space where you can still use every square of the crate to your advantage. Notice how the Coral Cradle fits into the section where the PVC pipe is used for the feet.
