4x4 Filament Rack Bracket

I printed a few other brackets to use dowel rods with to hold my spools of filament. I couldn't find one that I was happy with so I made this one. I build a table out of stuff I had in my garage at the time which consisted of 4x4 posts, a pallet and some 2x4's I used for braces. I wanted a filament rack on it and decided to use the width of the 4x4's as a spacer. I used 7/8th inch dowels from my local hardware store and used some sheet rock screws I had here to attach them with. I screwed the brackets on the inside of the 4x4 legs and then slid the dowels threw the holes.
