This wire loom tool makes inserting the wires in the corrugated tube much easier.

I've provide several common size versions, ready for direct printing.

The design was made using Sketchup. You can also download and change the skp file to meet your needs. The design in the skp file is 100mm diameter, so it needs to be scaled down. I used netfabb basic to do this, but most slicers offer some sort of scaling as well.
