There should be a total of 5mm to spare on the inside width. But, like I said, some of them must have been cut at 40mm exactly, which would require you to trim off a couple mm from each side.

I switched vendors. All seemed well except some of the blocks were exactly 40mm wide (which doesn't quite work when the space is 40mm...). By the time I got the third order, they were ALL 40mm wide. So there must have been some miscommunication between me and the vendor.
I've seen the stuff coming from inventables and it's legit. I redrew the part and make notes of tolerances for width, threads, and spacings, along with material specs and a bunch of other details I had assumed could go without writing in the past. You know what they say about assuming?!
Hopefully all of these issues are behind us now
