The cut looks great! Good Job.
As for the mount I couldn’t see the top mount but try turning it over. I don’t have mine on right now but I think the top one gets put on flipped over. It effects the angle as well.
I actually have the 3rd prototype printed of the new mount, but I haven’t had free time to measure the angle or test it yet (taxes, boring). The 2nd proto had a 0.45 degree angle on it not much but I really want to get it perfect now that I found and easy way to measure the tool angle.
