I had a friend make me an arrow square with a 3D printer, I just can’t find info anywhere about the sand paper grit I need. Even the Lumenok FAST doesn’t list the grit of their “sanding disks”, and there is no where to buy extra disks. Anybody have one and can tell me what grit you are using?

I agree with 120. I have a FAST but don't know the exact grit it looks like 120 but can't verify so I cross referenced other squaring tools. The Firenock APS squaring tool uses 120.

I use 220 but it really doesn't matter. Buy an assortment pack and see what works best for you.
