This is a model for cable managing your desk cables. I've made two versions, one with twist and lock mechanism and one with simple press fit, which is support free in case you're using a big nozzle or your supports aren't quite tuned in. 

To make the top and bottom have this hexagonal or other infill pattern, just disable the top and bottom in the layers and perimeters tabs and choose your infill density and pattern in the infill tab. I went with hexagonal 27% infill. It took around 100g to print.

If you have issues with the model please inform me in the comments and may your desk be clean :)
