Adventurer 3: PTFE Boden tube connector/coupler replacement
The FlashForge Adventurer 3 is a fantastic, affordable 3D printer, but a common issue is the PTFE tubing releasing from the coupler, and usually once forced out of the connector, it requires a replacement.
These are very cheap from Amazon, this is the coupler shown in the video

Thankfully it's a quick and easy fix, and in this video, I walk you through how to safely replace the coupler and make sure your print head/nozzle is clear of any blockage that might have initially caused the tube to release.
Please note: It's not usually necessary to replace the entire tube, If the tube has a large indentation from the previous coupler, you can cut off the bottom 5-10mm to ensure the replacement coupler has a clean connection to the tube.
