In case anyone is interested I have put up the STL and parametric scripts on Thingiverse
for a project to build a replica PDP-11/03 console with the same look and feel as the original
(following the 6-foot Rule) for an MDB backplane I acquired from a cctalk listmember.

If you have missing or broken switch paddles on your 11/03 or 11/05 then this might be of
use to you. Also included is the LED receptacle used on the 11/03 and 11/05 and I think
(but am not certain) the PDP-8/E, as is currently being discussed.

Being parametric you can adjust for different C&K switches, or other brands if you like.
