New Dremel has different diameter

In the end I was able to mount it by removing the bracket and clamping it over top rather than trying to slide it in.

It’s rather rude that they’d change the diameter of their tool. I guess they need to make improvements and cut costs. I’d want to say improve performance but my new Dremel is no where near as fast or high torque as my old one. But it’s still an awesome tool.
