Another follow-up question, then: How did you manage to spend 50 hours making it? Did you sit there, painstakingly, making one leg thinner than the rest for some reason? Did you sleep? Did you spend 20 hours of it browsing HN? In either case, this would likely fall under the category of unproductive labor: https://en.wikipedia.org/wiki/Productive_and_unproductive_la...
There's also the distinction of "socially-necessary labor", which feels (to me) like Marx's parallel to subjective value - the more socially-necessary, the more valuable the labor (a nice table vs. a crappy one).
In any case, the value is not just a measure of "hours put in" as you're making it out to be here; clearly I put more labor into it than you if mine looks/performs better in the same amount of time.
