Flush Mount Cable Holder

I wanted a cable holder / organizer that I could mount flat against the edge of my desk. I found a lot of similar holders online but nothing that really matched my particular need so I made my own. My original design had squared edges as shown in the pictures. I modified the design to include rounded the edges which should reduce friction when the cables are moved. I used the default settings on my Ender 3 Pro to print this. It won't be subject to much force to it doesn't need additional structure in the print.
