You're going to eat through it (the Suck It Dust Boot) with your router at some point. I went though a whole process when I got my OneFinity CNC to be able to replicate it without having to wait weeks for one to ship from them.
I took the router plate/shied, "copied" it with my Shaper Trace, put it into the Glowforge with some 1/8" thick clear cast acrylic, and made a bunch. It wasn't a direct 1:1, so the screw fitment was a little tight.
Turns out, OneFinity is awesome, and they just give the actual SVGs away, so you can cut it on the laser or the CNC. Click here to grab them!
