The New Hotness

Rebuilding the case with some improvements  to the original design came out much better:

The latch is about the same as before, but the top endplate now has two cable ports and locating pins to take the force from the battery contact springs:

The bottom endplate has a hole for the TinyTrak3 Mode switch, plus two locating pins that hold the plate in place:

A detail shot of the two endplates shows the new holes:

Snippets of brass rod became locating pins, each slipped into a hole atop a dab of epoxy to lock it in place:

The boards slide in pretty much the way you’d expect:

The OpenSCAD code punches a third cable hole in the case for the HT wiring. I had high hopes that it would fit through the endplate, but …

Seen from the other end, there’s not much to see. The next case will have a slightly narrower LED opening:

The imperfection running down the side comes from a brief pause in the proceedings while the support plate fell out of the opening. As a consequence, I discovered that the LED window doesn’t need any support at all.

This view shows one of the battery contacts peeking through the hole for a yet-to-be-made stud:

The solid model show some additional revisions, but it’s pretty close to the green plastic versions:
