Well, I'd hoped to complete this project with just a membership at the local makerspace, but...3D printing takes a long time, y'all, and having to commute an hour each way by bike and train for every iteration of every part was...time-prohibitive. So, I bought myself a 3D printer. Yes, I own other 3D printers, but...those are on a different continent, which is even more of a commute than the makerspace.

Anyway, the nice thing about this build is that the components are small, so a relatively inexpensive printer can do the whole thing...in theory.

First results show excellent fit of the various pieces, but I'll need to break the aformentioned pieces up even more than I already had in order to prevent improper fit due to overhangs and support material.

The excellent news is, one of the most vital pieces to fit, the dovetail assembly, does fit! and very nicely...at least when printed in the most optimal orientation, perpendicular to the final print orientation...time will tell if it works when printed vertically. It does seem like a delightfully robust design for a relatively low-profile locking mechanism.
