Lead 1515 Dust Shoe / Router Mount

Hey guys,

I'm currently designing a dust shoe really similar to the one available in the openbuilds store. However, I'm using a 4" dust hose. I'm running into an issue where the right angle connectors on the bottom of the router mount are preventing me from having very much material behind the router.

Currently my router is mounted to where the bottom of the body is inline with the bottom of the z-axis gantry plate. Should I move the router further down in the mount? Is there a best practice for that mounting height?

Thanks!
Logan
