Tension Rod Support

My first functional model. Feel free to make suggestions.I'm using two parallel curtain tension rods from Wal-Mart as a storage solution for all my roles of filament, but I was worried they'd slip overtime. So this is what I came up with to support the tension rods. Should accommodate rods about 42mm in diameter, but can probably be scaled up or down to fit your situation.These are the rods I used.https://www.walmart.com/ip/Mainstays-30-to-52-Adjustable-Curtain-Tension-Rod-Oil-Rubbed-Bronze/258292699?classType=VARIANT&from=/search
