Simple Cable Duct for Desks

This cable duct can be clamped to the desk without any screws and hides the cables underneath. 

It works good on Ikea desks with a plate thickness of about 34 mm, but other thicknesses may work as well. 

PETG works well. If you want to try other materials, please keep in mind that some power supplies may emit heat, which could deform the print.
