    UPDATE!
    I have revised my casing for the actual screens. My previous prototypes (the ones in the pictures) required epoxy to have everything stuck together. This new revision is both lighter and less reliant on epoxy. The only thing that should need epoxy are the two side and top bezels while everything else should only need screws. Going to use Cura to determine how much this new one will weigh so I'll add that in later. I also added in mounting for both sides so no need for separate files for each side!

    EDIT: New weights are in! One screen (including the hinges) will take 251g. The ones shown before took 320g. That's about a 22% reduction in weight for the screens itself and there's 2 of them so not bad.

    First test print is done! I did this using a 0.6mm nozzle so the holes for the bezels didn't get printed sadly so that's been redesigned.

    This whole thing is really janky. Snce there's no top bezel, the top two plates keep coming off so I've already made some redesigns to how the bezels are mounted so I can print using the 0.6mm nozzle. If I swapped to a 0.4mm, the mounting would also print but each print would take an extra hour so... Nah... Also, the top left plate had a layer shift while printing so that's gone badly. All in all, the dimensions are correct, it just needs more supports. Going to add some slots between the plates so they slide into each other and better align and redesign the back bracket so it better supports all 4 plates.

    Here's the new revised screen casing
    Annotation 2020-03-04 220456.png
    I've gotten rid of the side bezels since even with just the bottom bezel, the thing does stay in decently so the top bezel should be enough.
    There's now guides inbetween the plates to make them fit better. I've also make the edges between them 0.1mm smaller.
    Printing shall restart tomorrow. Right now I need sleep.

    Im starting to go insane from this 3D printing!
    I keep getting layer shifting half way through my prints for the bigger back plates for the screens which misaligns the holes :|
    Doesn't help the fact that even though I use a 0.6mm nozzle, it still takes 2 and a half hours to print fully.
    I think it's something to do with my slicer software because if I stop the print and restart it, it goes directly back to where it shifted even though it gets reset to home. Anyone got any tips for this? It always shifts on the y-axis and my belts are fine. I'm using Cura 4.4 and the Ender 3 Pro printer.
    I've ordered an SKR Mini E3 board to improve its printing and hopefully print faster using a 0.8mm nozzle and the Hero Me duct

    EDIT: Got it sorted, the new board doesn't have the issue. Also I went with a 1mm nozzle now so I can print out prototypes in 1hr 30 mins per part which is nice. Also, the new board makes the motors SO much more quieter now. The only loud part are the fans now.

    UPDATE:

    HUZZAH! The first practical prints have been done for the screen!

    I need to reprint the black pieces but I've ran out of black filament (ordered some more) since I'm still using the older pieces missing some more mounting holes (and are just generally bad prints hence why there's some holes for screws yet I didnt put any in).

    The screen now is solidly secured in the frame so wobble isn't an issue! The new mounting for the bezels also works well and is now aligned perfectly with the screen (minus the bottom left one with my username on it, that one was a test print and cba printing it out again to add an extra 3mm :p ). Since I'm gonna end up reprinting this almost entirely again, I might do some more adjustments so I can reduce the height of it.

    Since I still have the white filament loaded, I'm gonna try printing out the covers for the circuit boards now.

    The circuit covers came out decently. One was printed with supports, the other without so I might reprint that one with supports as well but they're good enough.

    Dont have any M2 screws for the OSD controls to be screwed in so I'm just using tape to keep them in place xD Not too sure it's lined up properly though, there wasn't a diagram for it so I had to guess using a crappy ruler I got in a stationary kit :p
    Also there's no hole for the LED, it just shines through the PLA which is nice. Didn't really care about that LED.

    How thick is the housing ?

    Each screen takes about 6mm and the panel that sticks to the back of the laptop will be around 22mm. So, in total, with both screens folded it will be around 34mm. The main reason for that thickness is the circuit housing since I need standoffs to keep it off the base and then another to attach the housing. If i had smaller standoffs, I could potentially shave off another 5mm (the board itself is 9mm due to the heatsink)

    Interesting project, I would like to do the same on my M6700, I can connect two internal screen (LVDS and eDP) however I don't know how to handle this, should I make the 2nd monitor sliding behind the main monitor or should I use hinge to make it rotate.. and most importantly, how to not break the 2nd monitor ?
