You can find the Fusion 360 file to change the model according to your vacuum hose.

I already setup some parameter for ease of use.

I also exported what I believe are standard hose diameter clips (cable diameter is 8.5mm on both) :

• Vacuum cable clip d27 : inside diameter 27mm, outside diameter 35mm (I believe it is a Festool standard)
• Vacuum cable clip d35 : inside diameter 35mm, outside diameter 42mm (tested on my Karcher WD3 premium and it fits perfectly)

If you have other dimensions suggestions don't hesitate to ask !

Print Settings

Supports: No

Resolution: .28mm

Infill: 20%

Filament: Dailyfil PETG Black

Notes:

You can had 2 tabs at the end of the clip to secure the first layer. I did that and never had a problem.
The clip takes approximatively 25min to print.
