The original model has some design choices I'm not sure the reason of, which made it not optimized for printing. So I “remixed” it, as in I used some of the same measurements and designed one that is much easier to print. Also made the tabs a lot stronger.

You'll need to get the extension cables for the feeder from here:

As for the filament feed config in klipper, you don't have to change it. I tried using the default value and everything works like it should, but if you want to change them, you can just simply go to the printer.cfg file in klipper and change the following values in there. You also don't have to use the extended firmware, I'm running stock firmware.

And instead of using pc4-m6 pneumatic connectors, I'm using ecas04, as they're just better in everyway.
