Hi all, I’ve published the model I’ve been working on. Idea was sparked by one of the early users - Barry.  
Here is the link - [Snapmaker U1 - Autofeeders PTFE Tubing attachment by makemeone.xyz | Download free STL model | Printables.com](https://www.printables.com/model/1477419-snapmaker-u1-autofeeders-ptfe-tubing-attachment)

Can’t open in Bambulab slicer, even though it offers it (waiting for the U1 to be delivered)

I like the idea of retaining the feeder shells and just using the 3-D printed couplers. I will probably try to print them at a 45-degree angle to make them stronger.
