JK BMS Power-Button holder

This button holder mounts the JKBMS Powerbutton to a 20mm wooden plate.

* I have two banks so I created refined variants with numbers on it,
* plus my BMS is on the other, opponent side, so for the optics I added a small cable tunnel. It also fixes the cable in place.
* The outer gap might be useful, if the button is already hard wired.

dimension:
* plate thickness 20mm
* button/hole diameter 11.8mm
* with 13.8mm button rim
