Simple and usefull.
My print is a little short for the blocking trigger, but nothing problematic.
@ld40 Thanks for printing my model! I noticed that too, the reason might be (apart from my tight measurements) that the seam protrudes towards the inside too much and thus block the latch from returning to zero.
You can see that in my model images as well, the latch top bulges out more than in the CAD-file.
