Hey @howardhb! I didn't forget about my offer, it's just been a busy few weeks - I'm still happy to get those document box measurements for you if you want. I was planning to just take pictures of the readings on my digital caliper as I measure each dimension.
Would you prefer to see inches or millimeters? Also, I can post the pictures here, or send them to your email if that's easier. Let me know, and I'll get on that as soon as I have the time!
