    Got some delay from 3D print lab yesterday. After 13 copies they out of black PET material and need one more day to replenish stocks. Also i find that i was sold of wrong size DC socket plugs, so i need to go to the store again and replace them. Done a lot of preparatory work and small additional helper tools to setup a better workplace and faster pipeline. Final soldering done with quality materials and proper workflow, all elements and joints are tested. Everything will be durable and reliable.
    Probably next week i can fulfill first orders and start shipping.

    You are in the list. I added everyone who mentioned earlier in thread that he is interested.
    Yesterday i ordered a batch of boxes in 3D printing lab. It takes 2-4 days to print them. Next i need few more days to grind and paint first 5-10 boxes and assemble all parts together.
    Currently i am testing for optimal wires length. Tomorrow i'll try to start wire connectors to cables together to save some time.

    Done some testing. All cables with extra length fits well. Cap can be closed without any problems. This is example of S.Bus+LANC+DC power config.
    In final version all cables will be marked with different colors:
    S.Bus:
    signal (middle) - green
    power (tip) - blue
    ground - white

    LANC:
    signal (tip) - yellow
    power (middle) - orange
    ground - grey

    DC power:
    +12V - red
    ground - black

    It just very pleasant for tactile feel when things are aligned and nothing comes out or comes too deep inside. But after some experiments i find that grinded screws unpredictably prone to bend slightly due thermal impact. So seems i have no other choice but to keep original 1" screws untouched.

    He's a true craftsmen. I appreciate his attention to detail—as I'm sure we all do! I'm on the list too, right?

    Flat head (cone) socket screws are not usable because they fall into the plastic too easy end deform it. Also they have too large head diameter.
    There are also button head screws, they are usable but also have large head diameter but slightly less than flat head screws.
    Both flat head and button head screws use very small and unsecure hex key hole.
    Also i already order a batch of hex keys for high head screws.

    If you don't want to add thickness you could always go to a chamfered countersunk hole and use flat head socket screws or use a shallower counterbore and use button head fasteners. You could make up the 1.5mm in the countersink and not add any overall thickness. Here you can see the difference in the way the fasteners are measured. With the socket head cap screw 1" is the length of the thread and for the flat head hardware it's the overall length.

    I'm on the list right? I'm really looking forward to this.
    Howie Roll, sure you are №7 in list.

    Yes custom made screws are pain in the ass and unpractical but i wish to make things as compact as possible. I need to cut only 1.5mm from the 1" screw so machine grinding is the simplest method for me. But even with cutter tool you need to make additional fillet at the tip.
    Other closest option are 7/8 length screws, but they are too rare and sits too deep.

    Also i'm still not sure what kind screws to use. Black metal looking cool but less practical for this size (not too hard steel, easy to scratch, prone to corrosion). Stainless screws are stronger and lasts forever but not sure that i always prefer that shiny look.

    Anyway today l'll think about it. Here is how things will look if i use 1" screws without cutting. Maybe not so bad as i imagine?

    A hack saw would work if you cut between the threads.

    Every step in preparation for the production creates small questions and problems. 1" screws are little bit long, so today i experiment how to grind them correctly without damaging the thread. Need to find and get a dedicated tool for it tomorrow.
