Simple dual cable tie slot drill in anchor for cable management.

2x M3.5 self-tapping screws per anchor

Print in any filament you like. DO NOT turn on supports. The model can bridge just fine. If you turn on supports, you will have a hard time cleaning out the hole.

Loop the cable tie through the hole to fasten down your cables for some nicer cable management.

I figured that I'm not going to be changing my cable configuration that often, as such I don't really need to have “reusuable” clips that are bigger and less sturdy. Just drill the anchor in and lock up your cables using a zip tie.
