MultiClip universal cable holder

I remixed the original by guyc to make it comaptible with the [MultiClip](https://www.thingiverse.com/thing:2747516) universal mounting system.

The example print from the pictures uses magnetic multiclips to fix an assortment of laboratory cables to a metallic surface.

If you need different dimensions, you can just re-parametrize the original and find the clip mount template object in my [collection on tinkercad](https://www.tinkercad.com/things/2hHDwAeQ9XZ-multiclip-mount-design-templates
