Overengineerd Lithopane Lantern

However, there are a couple of technical objections I have against the original design:

1. The use of wooden dowels. Who wants to make a trip to the hardware store?
2. The positioning of the dowel holes. They are placed so they weaken the structure.

3. I've cut the model into parts. For the whole model, the only
