It looks like the forum has changed quite a bit, and I no longer see DM capabilities. Ah well. Glad to see the interest. Please reach out to https://twitter.com/everywhyguy and we can continue the conversation. Would love to learn more about your use case.

Hi rleonard! Sounds like a cool application. V3 is the way to go, and it's working well in the field now. The only un-addressed feedback at this point is to tolerate sloppy printers a bit better around the o-ring area. I do have some extras from the development process if you don't have a good printer handy. Happy to entertain customized versions with any donation to Bat Conservation International. Just needs to be vector - DXF or SVG should work in Fusion 360. DM if you're interested.

Thanks for that. There's going to be some variance in hex head size, and while mine was sized for a tight slip fit, you could either reduce the size a tad based on measurements, or add a dab of glue. It shouldn't even really need glue since the hex head locks the thumbscrew part in once the nut is on. I could see how the lid backwards could be an issue; didn't test that! Out of curiosity, what printer did you use?

That made my day. Looks great! Thanks for sharing it. Any issues? I'm interested to see that you skipped the optional thumbscrews.

V3 looks like this:

I know of one ~60 case order for the V3, and I did a 10-case V1 order myself to test out 3DHubs. It came to $10 per in a tiny quantity, which includes production and materials for PETG. Quality varied, but all were usable; it's a functional part in the field, so it was good enough, and the V3 design removes the need for precision pretty much everywhere, since the magnet holes are gone. If your V1s are going in the field, taping the seam and potentially just flipping it upside can be be helpful. Just make sure to test before deploying.

Glad to hear, @alex.bush. BTW, there's a new version (v3) up on PrusaPrinters, with a number of improvements. The PrusaPrinters site prevents me from changing the v1 site to link to my own design (!) so you might not have seen this. As always, interested in any feedback/usage. https://www.prusaprinters.org/prints/56767-audiomoth-vault-v3

@Andris Dekants It looks like other cases (https://store.groupgets.com/collections/audiomoth) aren't available for premade purchase, but you could commission your own prints of this one with the linked .stl files using an online fab house like 3DHubs.com or Shapeways, or find a local 3D printer person. I have no experience with either, though. If you're looking to test a small number, reach out directly, and I'll see what I can do.
