3D Printable enclosure for 128x64 screen version

[rtmq0227]

Since the only enclosure in the repository is for the smaller, x32px screen, I put together an option for the larger x64px screen (stl files linked via dropbox). It's configured to allow for the USB A Female port option, and has an access port for the three debug pins in the backplate. It assembles with six M2x18 screws with room for locking nuts (links below), and some rubber padding to seat tightly without rattle. It's designed for Resin printers, so you may need to file down and drill out the interior openings if you have a pronounced foot on the print. I also recommend not soldering the screen to the PCB until you have it in the enclosure for the fit to be right.

oooh wow!! It looks awesome, thanks!!
I'll try to print it, even if I don't have a resin printer, let's see how it works.

I found the most success avoiding the elephant's foot issue ruining the face of it by orienting the main stl as shown (text facing up) but it does require supports on the underside in that case. I originally designed it to print the opposite way but couldn't reign in the foot on my printer

[rtmq0227]

I added a "simple" STL package for if the fiddly bits are too much for a filament printer. I also added some better pics to showcase the final build better

[Manofhunt]

I printed the original case on my FDM printer and the only issue I ran into is the holes for the nuts were a little tight. I was able to chamfer the holes with a razor blade and that solved the issue. Thank you for providing these!

[rtmq0227]

I'll admit I ran my tolerances a bit tight, I'm printing on a Photon Mono X. I can adjust the "simple" version to add a little more room for the nuts, how much extra clearance did you need to add?

[Manofhunt]

Difficult to say since I did it by hand, but probably about 0.5mm cumulative between the different sides I shaved on each nut location.

@rtmq0227 thanks for your work on this.
If it's ok for you, I'd add the files to the repo.
Thanks!

[rtmq0227]

Gladly!

I'll update the simple files with the expanded nut holes tonight

[rtmq0227]

Okay, I've added a v1.1 for the simple backplate with larger holes for the nuts, and here's an orientation guide (since Fusion always seems to export in the wrong orientation -__-)

[cecio]

thanks @rtmq0227
One question: am I wrong or in the new folder I see two version of the backplate but no spacer?

[rtmq0227]

no, there should be all three. I removed the old version so now there's only three STL files in each version's folder

[cecio]

ops, sorry. Thanks, I included your STLs in the STL folder and credited in the README.
Thanks again for your contribution.

Really nice looking case! would it be an idea to also make a top plate for the 128x32 screen? @rtmq0227

I wasn't going to, as there's already an enclosure STL for the 128x32, but a coworker was having trouble with that one so I may as well (better to have more options than fewer, right?).

It'll take time as I'll have to put together one with the smaller screen for reference purposes.

@rtmq0227

Where did you make use of the rubber sheeting on the enclosure? Does it go between a layer?

[rtmq0227]

@Tz1rf sorry for the delay in responding! I use it between the middle layer and the PCB to take up the gap/tolerance and keep it from rattling around. A small strip along each of the longer sides of the PCB do enough without messing with the ventilation. I'll be doing an assembly video in the near future, but I'll try to get some pics for this thread in the meantime.

@rtmq0227 if you want me to test out the design i would be happy to do so.

[rtmq0227]

@pettard So I actually did recently put one together, but the current STL has a second hole for a NeoPixel because I was trying to create a custom build with a color-coded indicator to match the events (green, yellow, red, flashing red). I'll create a version without the extra hole and share it here soon.

@Tz1rf here's that image I promised:

@rtmq0227 Any update on the 128x32 version?

Sorry, I lost a lot of personal bandwidth in preparation for DEFCON

Here's the STL of my x32 screen enclosure. It works with my existing spacer and backplate STL files: https://www.dropbox.com/scl/fi/oqpq88l8r2xmb2uyov4sn/Enclosurex32-Final.stl?rlkey=n5luu3rnxmibmkgaoqbzm8br6&dl=0
