Here is a little 3D print to help organise your desk, just send it to your trusty machine, take it off the build plate, screw it under your desk and it's ready to go.
i suggest using rafts to guarantee a successful print.
If you need something like this but not quite like this feel free to use the fusion 360 file to create the perfect cable organiser for you. many of the key dimensions can be modified in the design parameters.
