Finished print notifier

Add some microwave style funcionality to your printer with this device. Its purpose is to detect when the print is finished and play a loud customizable tune alert to notify you.

It's designed to be hammered into place at the front of your Y axis rail (4040 Y extrusion), behind the belt roller. When the platform moves to the front after the print is done, the wheel will push the limit switch and after 5 seconds it will play a tune via the piezo buzzer. The 5 seconds requirement is meant to prevent accidental triggering of the buzzer.

Compatibility:
bracket should fit any 4040 Y profile of any printer that has enough room at the front for it to fit without colliding with the wheels. (I measured about 13mm from the wheel to the tip the profile)
I designed it for my ender 3 max neo. I didnt test it on any other printer. Test print it yourself and check if you're unsure.

What you'll need:
- Arduino nano
