Finally went about the whole case thing. I don't know why exactly, but I'd been avoiding it. The requirements here are that there are 2 cases, one that holds a receiver board, and another that holds a 'cue' board of the 8 contacts. As mentioned in the v0.2 boards post, These are a lot smaller than the v0.1, so I really wanted to take advantage of that.
So there's the first problem i came across - my 2S battery pack needed about .5" more of space than the receiver board was long. In my head, the battery and receiver were inline, but it was a tall order as the board is about 64mm long and an 18650 cell (without any strips and insulation on the ends) is 65mm. If I extend the case rearward, I need to recess the USB-C mount which means it either needs to be way too big to accommodate the wide range of plug sheathes, or it just wont work for certain ones. I cant extend it towards the cue board as that still needs to plug in. I could have extended the lower part of the case to go beneath the cue board (and even support it a bit) but that would have been a huge overhang on the part that wouldnt print or manufacture well.
So made the call to turn the battery 90 degrees and widen the case...
Also made some room/provisions for a slide switch under the USB port on the board. The battery being sideways does give it a more 'pucky' feel, which I guess I kind of like. My general idea is that i strap this to racks or leave it on the ground, so I opted for an easily zip-tieable slot on both sides. For securing the battery I put that cradle in, and will also have a layer of foam insulation between the bottom of the board and top of the battery to keep things snug - or maybe just a thick layer of VHB tape.
So past that, I laid out that cue board as seen above and got to figuring out how to make a easily-ish printable, and chainable case for that. I didnt get super creative here, making a kind of U- connector that has an M5 hex cap screw secure. Both the receiver and cue case have one part of that lug on their top and bottom halves, so the bolt additionally secures those halves in addition to the M3 screws that keep them put.
Once I was pretty sure of the Cue case to receiver case interface, I copied it back and figured out the cue case to cue case connection. This was pretty much a carbon copy of the other connections with some provisions to brace/support them well. With the cap on the cue module, The capacitor is up a ways, so I went with an either lazy or artsy theme of having the top of the cap be exposed. I didnt want to just cap it with part of the shell as that would have made ethe part a nightmare to print.
What I came up with isn't what I'd consider super elegant, but it will do well enough at giving things a place to live during field testing. Doesnt have any of the switches or antenna but this gives a good enough idea!
