Or, you can grow your own if you have a 3D printer. There is a F360 file here in the forums somewhere. I modified it to fit my Makita. Happy to share that file if anyone wants it. Be advised, it’s not as convenient as the 611 design, you have to remove the boot to change bits.
I’m not very smart, I broke 2 suckits on clamps/fixtures. This design is more robust, shall we say.
