I would assume it would be trivial to do an injection-moulded run of 
these handles, if 3D print schematics are available. They were 
definitely well-copied in the hey-day of the PDP-11, with most 3rd-party 
cards using identical handles, minus DEC branding.
I think the real question would be if doing a production run would be 
worth it. To make it economical, you'd need to do a run of a few 
thousand, but i can't imagine the market demand would be there for so 
many handles. The other question is, why replicate the originals? 
Surely, there's got to be a drop-in replacement that would be stronger, 
even if it's a length of bent steel rod with the ends flattened and 
drilled through. (I'm sure i've seen someone do this somewhere, but i 
may have just dreamed it)
