His laser can hold .001" of what?
Good laser shops are good at making things fit together pretty good. I'd say they can be +/- .001" on a small diameter most of the time they try hard.
If they're not trying hard or the feature needs to be round or on position or the edges need to be true 90 then your pretty fucked.
Ellis kinda seems to be what you're making here? Just CAD up a tab and slot version of an Ellis if you like them so much.
