Reddit reviews CASEMATIX Portable Projector Hard Case with Foam - Customizable Foam Fits Sony Pico Mobile Projector MPCL1, MPCD1, MP CD1, MP CL1A and More Small Electronics & Accessories - Premium Custom Padded Case

You could always look for pluck and pick foam cases which are fairly cheap on Amazon and come in a variety of sizes. Larger ones gives you options for pulling out more of the grid for future expansion.

I use this one for my recorder. Not something I'd toss around on the road Night after night, but it's inexpensive and fairly decent quality.

I picked up one of these Casematix cases ( https://www.amazon.com/dp/B0170RIRVY ) to store/transport my RaspiBoy and it works great. The foam insert is customizable so I was able to create a proper space for the handheld as well as a spot for the charger. They make larger sizes than the one I bought, you should be able to find one that'd fit your needs (though maybe not including the CIB games. Maybe pick up a Mega Everdrive for gaming-on-the-go?) The case reminds me of the old VHS rental cases (though much smaller, of course), which makes me smile with nostalgia.

I .... bought an orthodox (and then an Iris) because of this. :)

That said, a pelican case or the like would work for this.

Or... somebody linked this a while ago: https://www.amazon.com/dp/B0170RIRVY/

I’ve got all 9 stuffed into this puppy. Looks like it’s not for sale now?

Pics are here. I’ve got a little room at the front for cables and such too.

Edit to fix link.

Let's see,

1. I bought SurlyGoodDesign tokens off Etsy and I've generally liked those. Dude sent me some wrong tokens by mistake and immediately responded to my message and sent out the correct ones.
   
2. I bought CurledPawCreative templates off of Etsy and those have been really nice. You have to paint them yourself but they come with tape attached so you just have to paint how you want, let it dry, then remove the tape and you're good to go. Tied to this I bought the HighbridgeDesign template tray holder (with the magnetized lid) and tournament tray that all packs up nicely.
   
3. I've bought the deluxe movement dials just because they stack on top of each other nicely. Purely cosmetic
   
4. My game mat is one of the FFG ones. As long as the whole thing isn't covered in crazy designs then it's not really distracting imo.
   
5. I have some larger Stanley organizers for and a basic cheap card box for storing things at home. When I'm actually going somewhere I have a backpack I keep stuff in. It has the following stuff in it:
   
   1. Hardcase with customizable foam and affordable that I keep my Republic stuff in, including bases and movement dials
      
   2. Feldherr box for my rebel stuff, including bases and movement dials. This is smaller than the thing above though. The specific one I bought is one that holds the Falcon but it's no longer sold on Amazon at least. But really any of them can work.
      
   3. The HighbridgeDesign template and tournament trays.
      
   4. Card Box that has my sleeved cards, obstacles, medium bases, damage deck, and then also contains smaller plastic containers that have my dice, various other cardboard tokens, ship indicators, and my normal tokens.
      
      1. Token Storage
         
      2. Dice Storage and misc cardboard
         
         ​
         
         All that said, my setup time is not super quick but I can take quite a lot with me and it's just lugging around a backpack.

I was consistently disappointed by the rather expensive hardcases for the OP-1 that didn't look like they would protect my $950 investment properly.. So I did some searching on Amazon and found this lil diddly for a mere $25! Fits like a glove and is still compact enough to put in my backpack.

I don't think anyone makes a case specifically for portable dives. You could get a case like this and cut the foam to your liking.
