I work on a park that includes US Civil War battlefields, and we keep a small cache of reproduction muskets and uniforms for living history programs. We recently upgraded our musket storage from an unused closet to a dedicated storage locker. I only recently got into 3d printer, but the Void Star Lab videos played a big role in me pulling the trigger (pun intended). Gridfinity seemed like a good way to structure the inside of the locker to keep everything secure and organized. It's nothing fancy. Two 3x10 grids with bins shaped to trap the sticks of the muskets. Still working out how best to secure things at the top. But since that likely won't be gridfinity based I figured I'd go ahead and post what I had.

Previous post did lousy pictures (though the lighting in the building is still garbage so there's only so much I could do). Hopefully these are better, and provide more angles so it's easier to see whats going on inside. Having an empty row opposite the full row also probably helps.

Been working on upgrading the musket storage for my workplace. Gridfinity ended up being a great solution. Kind of a mismatch of filaments. Combination of Flashforge black pla and a Coex3D PCTG mystery color spool I picked up to experiment with (which is why it goes from translucent white to borderline clear). Still working on exactly how to stabilize things up at the top. But a huge improvement.

Take two on my dual protocol node seeking to address several of the criticisms offered when I first posted a little while ago. I did not address every comment, but I did my best to address the ones I felt were most important.

Turns out my prior problems that I blamed on the controller was just me doing an incredibly smooth brained job of cable routing. So all power is running through the controller now to get the most out of the batteries and solar panel.

I reduced the size of the pack slightly from a max of 10 to a max of 8 batteries. Effectively 4 per radio to match units like the Seeed Studio P1 repeater. This also has the benefit of making it much easier to access the bolts holding the mounting plate to the enclosure.

One of the comments mentioned the necessity for a fuse considering the very high current the battery pack could push in the event of a short. So a 3a fuse has been added in between the batteries and the charge controller.

The pack has now been fully electrically insulated from the aluminum interior of the enclosure with Kapton tape to reduce/eliminate the chances of a short if something comes lose on the inside.

People also pointed out that the antennas are closer together as currently configured than would be ideal. Part of this was driven by constraints at the installation site. Two physically separate nodes is not currently and option. In my personal testing it didn't seem to cause any problems even when spamming both radios simultaneously. If it does prove to be an issue once deployed it would be pretty simple to just flip one of the antenna upside down so at least they aren't in the same horizontal plane. Should that also proves insufficient I will have to see about exploring options to get the antennas further apart, trying to convince the building owner into allowing a second unit, or simply shutting off and abandoning one of the two sides of the system to preserve the functionality of the other. That would likely mean shut down/removing the non-meshtastic unit. As meshtastic is the far more dominant protocol in my region.

The mounting plate and component sleds were all 3d printed out of a glass fiber filled PBT. Which if the manufacturer can be trusted, should be capable of handling the local weather. The mounting plate is screwed into the preexisting standoffs built into the enclosure.

In addition I have two of the new Heltec T096s on the way that I plan to use in what I am hoping will be an improved version of this concept. I will likely hold off on posting any of the 3d printing files until I have that version done.
