I posted in Made on a Glowforge a project I did on my Pre-Release unit that @Dan asked to be cross-posted here.

Finished dimensions are 9.75" L x 5" W x 5" T when closed. The small boxes are 4.5" square x 1.5" deep. Open it extends to 26" in length. Each box extends by a 1/2" over the one below when open to help with stability. It’s made from 1/8" (3mm) stock.

It’s based on a project on Thingiverse that was started but not completed. I’ve made the necessary corrections and additions to make it laser friendly and posted the files. I’ve also added it as a remix in Thingiverse.

A couple of additional thoughts - in walnut or cherry with brass screws or two-tone with contrasting box vs arm woods and this would make a cool jewelry box I think. Line the boxes with felt (I’ll add a felt cutting pattern in the Thingiverse remix but basically it’s​ just rectangles to fit) so you protect the jewelry. A clear acrylic version would also be handy as you could see the contents without opening it.

Finally a couple of other top treatments come to mind - a flat piece of stock with two box sized squares glued to the inside would let you just drop it into place and the additional squares on the bottom of the lid would keep it aligned with the boxes. Alternatively, two box sized flat stock pieces attached using small decorative hinges would allow opening one side or the other while leaving the other side’s top box covered.
