Another cable holder for countersunk head screws with two useful features.
The flexible wings have a recess for screw mounting. This means that the cable holder can be screwed on directly without having to hold it in place.
There is also a countersink on the underside to prevent the countersunk screw from splitting the component.

The volume should be printed on the side and does not need any support. To do this, simply align the flat part of the whole to the top.

The top an bottom surfaces are bevelled so you can get a good result even if the bed leveling is not perfect.
The cable holder is designed for cables up to 5 mm in diameter. You can, however, scale it to fit larger cables.

I recommend PETG, but PLA will work just as well.

Have fun with it and please let me know what you think.
