I needed to trim a floor drain using a Dremel saw blade but only needed to remove 1.5 inches. I created this to replace the collar on my Dremel 7700 Series.

I created 3 variants. I used the 5mm plate version to make the blade 1.5 inches from the plate. I also created a 2mm and a 10 mm plate depending on your needs. I've also included just the nut if you want to remix into another project.

The link to the blads I used are below:

It should work great if you need to make a Biscuit cut depending on the blad and thickness of the biscuit.
