DEC PDP-11 Unibus and Qbus LED mounting receptacles

cults3d

This is a much revised version of my Qbus PDP-11/03 LED mount (Thing# 2829191). After opening up the PDP-11/05 console and finding out that it used three 6-LED mounts for the address and data LEDs and one 1-LED mount for the run (btw I put run/halt on the uploaded screenshot, should have checked the panel first instead of relying on memory). See the photos of the original mounts. I decided to revise that OpenSCAD script to generate those sizes, so here it is. This also generates all sizes from one to eight LEDs. I don't know if DEC used anything but the one, three and six-sized or even whether they existed as a part but I thought it would be nice to include them here for completeness' sake if anyone needs LED standoffs for a modern project. No need to bother with the Customiser, just open it up and uncomment the required one you need between the scissor lines ----8<----. No external libraries are needed. The demo of all eight sizes is (naturally) the line Demo(); if you need it. Given the facet setting (120) it may take a while to render, so go get yourself a cuppa whilst you run it. Colour of the originals was a very dark charcoal grey, black filament is ideal.
