It looks great as a lamp. That version is slotted for 0.15 material, and I get a decent friction fit with cardboard, but yes eighth inch material would be kind of loose fitting. I made a version for some supposedly eighth inch plywood I get at a local craft store, but unfortunately that was about 0.1175 in width, not really near proofgrade dimensions at all. That kind of variability in “eighth inch material” is super annoying.
A hatchimals rocket sounds like a neat idea. You could take those svg files and remove the interior circles from the bulkheads so they become shelves for passengers. Next challenge, leave an opening in the side for a door.
Here’s the A360 link:
It looks like there’s an option to download a version for Fusion360 (upper right corner), which hopefully will let you load it and look around. The design contains a parameter (modify -> Change Parameters) named “material_thickness” which will adjust the slots for a different source material width. Also note how I incorporated the laser kerf into the slot width calculation. Fusion360’s parametric nature is very useful for this sort of thing.
I’ll warn you though, I’m still learning Fusion, and the workflow for getting that design into the forge isn’t really optimal. I have to export the rib and bulkhead sketches generated by the last four steps as DXF files, then import those into Inkscape for layout. Unfortunately, splines in Fusion (which I used to generate the shape of the rib) can’t be imported to Inkscape. Fortunately though the slots and other straight lines do export, so I just fill in the gaps using Inkscape, being sure to keep the slots exactly the same size and in exactly the same relation to each other. I had an exported picture of the rib which I imported into Inkscape so I could trace over it in there. All a bit annoying, but it works.
In my second design I avoided using splines altogether, so the workflow to svg is much more straightforward.
Fusion360 is well worth your investment of effort though, it’s a very powerful modeling tool.
