Minimal PTFE Connector

This is a smooth minimal PTFE connector that doesn't required a PC4 coupler. Make sure to take a look at the arrow sign before using it. The connector is one way. If connected in the wrong side, it might jam the filament. Also, make sure to push the PTFE tube to touch the inner side of the connector, or else it might cause the filament to jam. You can verify this by looking through the rectangular hole on the side.
