Gridfinity Screw Measuring Tool

So I saw Boogie's screw measuring tool and I knew I had to make one, but I realized I didn't want to hang it from something. I wanted it with my gridfinity system. So I made this. Printed this and added a pause to swap filaments. Came out ok, got a weird thing going on with the top layer. Really don't understand what's going on there, but it's intermittent.
