MMU2 Selector large bore w/ 6x10x2 Magnet Mod

UPDATE 10/13/2019 - Added revised selector with pinhole to push out magnet for re-use in another print if needed. Also widened the bore entry points some more.

I wanted all the features of the large bore remix (and all the features it was a remix of), but with the addition of the magnet mod for the FINDA ball. However, I didn't have the correct type of magnet, and wanted to use the small magnet that comes with the MK3s upgrade (6x10x2). The other remix has a window to the FINDA ball, and I tried that first, but the window allowed some filaments with a bit of a curve to come through the window and fail to load. So, I remixed this one to have the magnet pocket I needed. It has been printed and preliminary testing shows good functionality. I hope it works for others.

Please LMK if you find anything that might need changing.
