Tubing Adapter for 1/4" filament feeder tubes.

This adapter is to make changing filament during printing easier. It attaches to the end of the tube which feeds filament to the extruder. Some custom extruders are a tight fit, even though they have a hole to accommodate the tube. This can be a problem when trying to quickly change filament during a print, and you can't afford to knock the extruder out of position. This adapter should fit most flexible tubing snugly, and slip right into the hole on the top of an extruder which doesn't have
