Being I work as a machinist, I get some rather ridiculous requests from people to make them stuff. Example...

"Hey man, can you make me a new speaker grill cover? mine has a dent in it"

...uh, sure, let me just take a few hours to draft it, set up the brake press, order some perf material, cnc machine a few set up prototypes and I'll have that done in about a month, that will be $160 down please, I'll have the full balance at completion of the job

Sometimes they are very realistic requests though and also fun! My buddy really wanted an Atari Key rack to hold his arcade machine keys. This is what I came up with based on his extremely vague description...

Turned out decent
