I needed to make a slightly more robust version of Cookiedeluxe's sterilite filament storage end pieces for the Sterilite 20 quart container. Because I happened to crack the PVC pipe holder in one of my boxes when a spool fell onto the PVC pipes.

By widening the raised section that the PVC pipes mount into, I am hoping to leverage the side walls of the container for reinforcement. Thus preventing the part from getting damaged when a spool slips from my clumsy hands onto the pipes.
