I invoke the deep magicks of nerfhaven. Is there a reason we never used doorknob latches as catch mechanisms? They’re already shaped perfectly for a plunger to slide over them, and they come with a built-in trigger mech. Did they just not have strong enough springs, or was there another reason I never saw these in the pre-3D printer days?
That was my guess, too. Too bulky, too heavy, too much stuff for too little gain.
All that said, I’d get a good giggle if someone actually tried it.
I’m picking one out as we speak. I’m debating paying $8 extra for the fancy Victorian door handle.
