+2 most just want them for the heck of it. Many will take anything just cuz it's free. U could have said pm me for free penis and they prob would lolz.
well just remember when it stops being fun get out of it or you just get pissed off, that is why I quit after about 300 " I need 4 18's in a crx" type request or " yeah I'm an idiot who can't measure right and my box doesn't fit so it's your fault" lol
Just a little FYI, most of the people PMing you have zero intentions of using those designs. They don't even own the equipment that you're designing the enclosure for. They are just abusing you. You really should charge at least a couple bucks to weed out those idiots.
