I got my Glowforge a few weeks back and have been having tons of fun making stuff.
One of the first things I’ve been playing around with is algorithmically generated design. I used the Travelling Salesman Problem algorithm generated by the wonderful app StippleGen2 to create a base puzzle design.
After some manual tweaking to the cuts to improve the puzzle, I designed a simple case to hold the puzzle as you build it, and when storing it. I also added a hole for hanging - it looks really good with sunlight coming through it.
Playing around with different material combinations has been exciting - I’m really happy with the clear acrylic case that lets the flouro colors through the side 
I’m super impressed with the Glowforge - it’s a game changing tools for makers to have at home!
