Openbeam wire clips

Do you have a Kossel/Delta with the cartridge rollers moving on the sides of the OpenBeam extrusions? Then you probably are in the same situation as I am: There is no place to tie the wires for the endstops!
.
Well, now there is, on the back of the extrusions.
.
This clip should just plug into the OpenBeam extrusions, and then a wire with a maximum outer diameter of about 2mm (or multiple wires equaling this diameter) should plug right in.
.
Please report if you can't print them for some reason or if your parts end up being too loose on the extrusions!
.
Update: bigger ~10mm clip added
Update: Made the fingers of 10mm clip somewhat tighter to hold smaller, bundled wires, by rounding the opening off. (Version a)
