I had been using the elephant filament guide on my KP3S, but after building an enclosure, the filament path changed and the filament would work its way out of the guide from time to time. This simple donut-style guide has no slot for the filament to escape out of.

The original donut was less than ideal due to where the filement entered my enclosure, so I made a modified (extended and angled) version as well.
