I need to remove the ptfe tube from my A1 Mini. What a pain. I have been at it for over 30 minutes and am now printing little tools to help. I just noticed many other posts about this so I am going to read some more but this is not really necessary is it? Has anybody made a new quad feeder that uses regular connectors that release like they should??
Thanks

There are lots of 3D printable tools for this job that make it easier.
I couldn’t find the one I use and printed from here, but, this is a big selection to choose from.

Thanks! The second tool I printed worked better than the first one that was too tight. I managed to get it off and my problem is solved. Thanks for the link as I will definitely look at some other models and likely print a small collection for the next time I need one. 
You are welcome.
They are much harder to remove when the printer is new. Finding the best tool for your needs helps. I also printed a few to find the one most suited to me.
