Dremel Blade Sharpener Remix

I wanted to make a super basic blade sharpener attachment for my dremel clone rotary tool. I found SonOfSparta's design and I liked its simplicity.
However, I use a cheap chinese dremel clone (Powerplus brand), which uses an M19x2 thread, so I had to recreate the original file using the correct thread size. I gave it a much smaller opening hole at the top because I only had a 6mm grinding bit available at the time. I also gave it an internal chamfer to allow it to be more easily printed, standing upright and without support. Finally I made it slightly taller to better fit my rotary tool, and slightly wider to make it slightly easier to guide longer blades through it.
The two sharpening angles are 15 and 25 degrees.
This was all designed completely from scratch in Fusion 360, however it is very heavily based on SonOfSparta's design, so I've listed it as a remix.

There are obviously much better ways of sharpening blades, however for a very quick and simple print, this has worked well for me.
