Replicator 2X PLA Extruder fix

So like many people I have had very little luck in printing PLA with the 2X. I have a very cold classroom being that it's the tech lab and the AC is on full blast most of the time. This made me think cooling the print wasn't the issue. Like most people the 2X would extrude and print ABS just fine but not PLA no matter the brand. When I would examine the faulty extrusion I thought the extruder wasn't gripping the PLA strongly enough and instead of printing an entirely new extruder or buying one of those aluminum ones from China I would try this first. Works pretty well for me. I'm actually pretty surprised it's working this well. The model has both left and right side. The left side has a bit of a deeper cut for the spring but I haven't noticed a difference. I made it wide enough to slide it and not pop out like the first few trys did. It fits very snug you should definitely sand it down a bit but I didn't I just shoved it in so it would stay put. I've just finished 2 6 hours print jobs
