It don't look like much, but I hope the above design (or something similar), will save a few hardware headaches for people building my cases (eventually). One of the most common criticisms of my cases is that they require too much hardware (in the form of various M3 screws). While I am of the opinion that hardware has a place in 3D printed designs, I think this is one area where I could improve things. The above is a pic of a test sample which I am investigating, to see if it will work as well as using a screw to secure the part. If it works, I may drop the screw requirement for this part and it's opposite latch cleat on the case, in favor of a clip in design. It's still early though, and I may need to make more changes to the design to insure there is no creep of the parts when the latch pressure is applied, but if I can get it to work, it will save using two of the more oddball M3 screws (per latch), which have been required to build the cases.
If these clip in latch inserts work out, they will probably be first seen in a fully revamped 8x watch case, which I've been working on. That 8x watch case is similar to an earlier prototype which I had completed (though never published), and will have all the latest updates which have already been applied to my other cases, which can be found at the links below).

12/13/2025: I got stuck with a side quest for the past week, due to some events outside of my control. I'm still wrapping that other projects up, but will hopefully get back to this one. I don't expect it will be done before Christmas though (the holidays are busy and stressful enough, without extra deadlines to chase).
2/8/2026: I realized I didn't update this, but I wanted to mention that these work. I'm planning to add them to the next update for the H2 spares case (which will also become a P2 spares case as well). These snap in latch parts will let me remove several oddball screws from the BOM on that case, and they will be rolled out to the other similar cases as they get their own updates later.
