So yeah, a practically useless paperweight that demonstrates how amazing your brozneworks is? Totally plausible.

It could be the equivalent to a master's project for an apprentice. I build and fit custom orthosis and prosthetics, at the end of the fabrication portion of school they had us build a brace that's not really ever prescribed anymore.

However, that particular brace requires all the fabrication skills required to practice in the field. Having one of these sitting on your table is instant proof that you can finish a complicated project.

It would also serve as an easy metric when traveling to places with non standardized measurement systems. Instead of transcribing what 1/32 of a cubic is, the customer could just point to a different sized hole.
