Palette 2 (Pro) filament input guide.

This is a filament guide for the Palette 2 and Palette 2 Pro.

The input section on those devices have a massive design flaw that will cause the filament to get stuck in a gap under the filament run-out detector switch during a run-out event if it is bent in the right direction.

This will cause a jam during the spool switch over that is supposed to happen when one spool runs out in multi-spool mode.
This essentially render multi-spool mode useless on the Palette 2 (Pro).

The guide is a small cap that snaps over the detector switch and fills that gap and prevents the filament from getting stuck.

This together with the [external filament buffer](https://www.thingiverse.com/thing:3548274) I also have on Thingiverse makes it possible to use this very useful mode of the Palette 2 without an extreme risk of having it ruin your print.
