wire holder for DIN rails

This is a wire holder for measurement probes (test leads) because those available for sell usually suck and come with non-standard rails.

Features:
) you can make your wire-wall in any lenght you like
) satisfying snap-fit
) fits deep and shallow DIN rails
) they attach to each other and keep the distance
) reasonably easy to remove (pull the big hole to detach it from the rail)

I made the hangers with a 5mm spacing - if you'd like to have that changed for thicker/thinner wires just
