This is a cable tidy that I designed to hide cables along the back of my desk. I designed it with the following specs.

20mm desk thickness my desk was 18mm and I used rubber disks to tighten the grip. I will consider making more native sizes if requested.

The cable clips are 10cm wide and can be placed next to each other if needed and are easy to use. 

I have designed the clip to use less support material though you will still need supports as I designed the cable trunk part to have a hook overhang to hold the cables again if requested I will redesign to remove.

I printed this with no issues in PLA and PETG using standard .20 layer heights though you can use quicker settings as the clip is not expected to be stress loading.
