A simple and sturdy cable manager with pen holder. Screw holes designed into model for ease of installation. Personally I just used a Command Strip. Tested and proofed. If you slice it yourself. I HIGHLY RECOMMEND. You slice the model to where the pen holder is at the top/last thing printed. ****Example in Cover Images**** After many trial and error. I found this produces the best results. I used a tree support 15% zig zag density. I am very happy with the results. This thing bends considerably before it breaks.
