Want to tidy up the messy cables around your desk? Or was your desk originally equipped with cable sleeves of various sizes and not very well-fitted, just like my old desk? Don't worry, just drill a hole with a diameter of about 5 cm on the desk with a regular hole saw, then print out this model and easily snap it into place.

The sleeve can be firmly embedded in a 5-centimeter hole, and the cover plate can be securely fastened. After assembly is completed, it can be flexibly rotated to adjust its position.

If you have any other size requirements, just let me know. Since the model has been fully debugged and ready, I can easily and quickly generate versions of different diameters as needed, no problem at all.

Update - January 8, 2016... At the request of Suren1987, I have split this set of components into two separate files for uploading.
