The box is made from PG plywood – maple with a liner of basswood, and walnut for the inlaid “poop,” which has PG acrylic eyes and mouth. The walnut band was kind of a happy accident – I somehow messed up the dimensions so the lid wouldn’t lower all the way with the cards inside, so I added the walnut strips to close the gap. It looks 'way better with the walnut than it did before.
I never had any doubt. You did a triple nested one no less, did you flip mate each “layer”? It can get confusing with kerf adjustment, tricky to keep it straight as you build it up.
The initial “poop” layer wasn’t flipped, because I got confused; I’d already cut the box parts right-side up planning to flip the poop (never really thought I’d see myself typing that phrase…), then realized the poop had engraves on it and didn’t want to start over. It was a tight fit, but it went together with them both right side up. The rest were flipped in alternating directions, though.
The hardest part was minimizing the distortions in the curves when I expanded the lines. I manually added nodes (AD doesn’t seem to have an “add nodes” function) and that helped, although it didn’t completely stop the distorting.
Yes. I mainly just wish it would spread them out evenly the way Blender does, It makes one from many but then you have to select each case and I find myself laboriously going through everything adding or collapsing as I go. There is some that can be done in the trace function but I have not narrowed down the ideal settings.
Inkscape will add one node where you double-click, or exactly halfway between selected nodes if you use the “Add Node” button - so if you select all nodes, it will double (-1) the total node count, evenly distributed between adjacent nodes.
I use it to create tabs across a straight edge, much easier and flexible than using the tab box generator.
It makes a great racing stripe! I was thinking engraved walnut drips… but nah.
