Remix of this model on Printables.com: https://www.printables.com/de/model/95300-festool-d27-hose-clip
I remodeled it and widened the diameter for the power cord about 1mm. The standard Festool power cords are not such thick, but I have some 3rd party cords, which need more space.
I attached the parametrized Fusion 360 file, so anyone can customize for his own needs.
Thanks to KSchloe for the original design.
