GT2 Closed Loop Belt Clip

I am using this clip temporarily. I have synced over several months, the Z axes of the X5S.
Clip must be inserted tightly and secured with one or two sewing needles.

Now I use for it only lead screws with 2 mm pitch. But finally a duet board or other with WebUi will be installed in all printers. I want to get rid of Octoprint for remote startup and monitoring for every single printer.

Greetings and much success.
