I remember once when I was in elementary school a kid said he wanted a case for his most valuable baseball card made out of diamond. His reasoning was that if diamond was the hardest toughest thing known to man, then it would keep his baseball card safe. Of course, this invited the obvious criticism that the case would be worth much more than any card he would care to keep inside it.1
There’s no doubt Thingiverse citizen ttsalo’s fully printable padlock is an amazing feat and working experiment in design, materials, and function. Besides it’s function as a way to learn or teach others about how a padlock works, a fully plastic padlock would also be really useful to keep some things locked. You could keep the contents of a cabinet safe from small children or a shed safe from small animals. It might be useful for very time-limited purposes as well – such as for clothes for use in a gym. And, don’t forget, given that there are no parts to corrode or rust, it could be used underwater!
- Setting aside the other issue of how the heck you would make such a case in the first place. [↩]
