side split

there are many levels of complexity I could descend into with this project but I'm finding these days that time is a commodity I have so little of.  Thus I feel this is a good compromise.  Plus I like simple.
this side split takes into account two key factors:
1. wood end grain should not be glued to wood end grain,
2. I don't want any end grain exposed to the slot, where precision is most important
to achieve the second end grain will be exposed under the lid. this could be fixed with a thin cap layer, but that would damage the minimal, functional aesthetic
