Eric, how were you able to get in touch with Bits and Pieces to do your box? I saw last year on the forum you posted that you were interested in the idea but had no idea how to do it.
Also, how come the box is rectangular shaped instead of your original cube? It's not apparent that it's any easier to build larger.

Eric, I got the most recent "Bits and Pieces" catalog yesterday and I noticed they have one of your designs! Is the "Shut Case Box" the mass-market version of the "Cam Box"? What was it like working with them?

I think your answer is correct (I just added a few details)
1.609 Hypotenuse H
1.138 Leg L = H/√2
2.606 Inner box width W1 = 4.156 - 2*(0.525+0.25)
0.639 Small hypotenuse h = (H+2*L-W1)/2
1.636 Inner box height H1 = 2*L - h
2.136 Middle box height H2 = H1 + 2*0.25
0.932 X = (4.0-H2)/2

Who won the Stewart Coffin puzzle design contest? I did a bunch of forum searches and couldn't find the details of the winner. I'm sure it must have been posted, but I can't seem to find it.

I sent an email to Grand Illusions asking who the designer and manufacturer were, but they didn't get back to me. I did wind up ordering it, though, so I'll have to let you guys know what I think after I've had a chance to play with it.
I'm a big fan of puzzle locks also. If this is anything like the Dan-Lock it will be one of my favorite puzzles.
