Button Shortcuts Ender 3 (for Octoprint)

Do you find yourself scouring the menus of your 3D Printer, just for one simple thing?
Add **custom shortcut buttons** to your Ender 3 using Octoprint and the [Physical Button Plugin](https://plugins.octoprint.org/plugins/physicalbutton/)!
Now you can simply heat your hotend or bed with just one click.

I've assigned the buttons to the following functions:
- Power On/Off
- Preheat Hotend to 210°C
- Cooldown Hotend
- Change Filament (M600, requires ADVANCED_PAUSE_FEATURE activated in Marlin)
- Extrude 10mm,

but you can customize these if you want. Note that the Power control is handled via the [PSU Control Plugin](https://plugins.octoprint.org/plugins/psucontrol/).

## BOM
