Bridge partner having a big-oh birthday → I decided to make a box with exactly 70 pieces.
It took me a week to think up this idea, but once you have it it’s easy: 3×5 is 15 .. plus the backing 16,
times 4 sides is 64 (we ex-computer people are good at the powers-of-2) .. plus a top and bottom is 66,
for 4 more use a rim around the top.

Woods: Northern silky oak, Southern silky oak, and Jarrah. About 17cm square, 11 high.

If you wanted 71 pieces, all you have to do is not pivot the lid but add a lid-handle.
If you wanted 72 pieces, you could use a 2-piece handle, or ..
