Metal case catcher for Dillon case feeder, 18mm or 15mm tubes, 9mm funnel

I saw some places selling a magnetic case catcher on the internet. It was pretty simple to make and print. I did not see it on thingiverse, so I added it.
It fits very snug on the case feeder tube. You may want to adjust the slot size for the thickness of your rare earth magnet; so I provided the fusion 360 file.
I made a funnel to keep the 9mm cases from going sideways in the case feeder before they hit the tube.
