Feeder gone wrong!!!

This is my feeder that I made out of some nylon plastic sheet:

I printed a new replacement part but it didn't turn out to good, I put it in place and used it to print another one to replace the not so good one, I woke up all excited for my new parts to replace my feeder etc. um.... yeah..... no.....
I woke up to this:

And this is all the plastic I woke up to on the floor instead of turned into my part:

It popped apart, I had to hold it together with clamps to be able to print another one.

I have had nothing but issues printing a new feeder, the old one would chew the plastic to the point it no longer could grip the plastic to feed it through and would stop printing, it would jame and break the filament, it would spew the plastic filament out the side, it was a nightmare, took me several days and like 12 prints to get it to turn out a complete feeder.
