I used 3 of the 10mmX20mm-outside open drag chain.
Amazon has them.
Ignore the 7x7mm in the description below - it is the correct link for 10x20…

If you order something else be certain to get the “Open Type” which allows you to carry cables with big connectors on the end.
You will also need to extend the Z-axis cable.
I used Amazon.com
Remove the screws at the connection and cable tie the male and female ends together.
You will also need to make something to screw down the drag chains.
I drew up and 3D printed these.
On this one I lengthened the screws to be able to fasten it down. Note I haven’t put the nuts on it yet.
