Anycubic I3 Mega Flexible Filament Adapter (remix)

thingiverse

When I set out to print TPU on my I3 Mega, I searched for flexible filament adapters with ease of use in mind. What I was looking for were parts that could be quickly installed or removed without needing any tools. So I ruled out the TPU adapters that required removing part of the extruder. Next, I tried several small add-on adapters available on Thingiverse and was initially disappointed due to incorrect sizes until I came across the model from Pleky085 (https://www.thingiverse.com/thing:2835875). It fit perfectly right off the bat! The only "downside" if I'm being picky is that I had to completely remove the Bowden tube holder from the extruder to put the adapter in place. I preferred another design where all I needed to do was unscrew the tube holder a little bit without having to take it out entirely. So, I modified the design from Pleky085 to give it that option.
