Just factoring in the BOM cost including 3D printer materials this comes out quite below a retail Tonie Box. The same is true for the cartridges vs. Tonie figurines. The tools are definitely a big expense, but are in constant use for other projects, so ammortize. What's not factored in is the time spent working on this. I don't feel too bad about it, as working on this essentially replaced watching shows or movie at night when everyone is asleep.
