Todays Project - What did you do today?

I see your point about the magnets, but as I cut mostly aluminum, it's not as big an issue for me.  

Not sure if the thread is large enough, but maybe you could thread in a thin bushing, which is smooth on the inside, but has a groove.  Then you could use one of those pins with the ball detent to snap in.  That way, you preserve the threads.

Heck, I'm sure you could design a pin that snaps into a bushing, and both parts could be printed.  Hmm...
