MiSTer XS Case - v5.2 XS for SDRAM XS - extra slim - v1.1

Postby NegSol » Sun Dec 31, 2017 12:59 pm

Introducing a new 3D printed case for the MiSTer: MiSTer XS Case - v5.2 XS for SDRAM XS - extra slim - v1.1

--
On request I remixed the MiSTer: Case Universal v5.2 to tightly fit the new SDRAM XS board v1.1.

--
The most compact version of the MiSTer cases. For a 40x40x10mm fan and the for SDRAM XS - extra slim - v1.1 only! This case is for you if you want the minimum case and still want to use the v5.2 I/O board's connectivity. Buttons are to be printed in place with the Top Shell. Also there are new holes for the LEDs of the I/O Board. There is an additional Top Shell without LEDs and without buttons. Pick the one you like best.
--
All 3D files are available on thingiverse and can be used without restriction.

Enjoy! :mrgreen:

Disclaimer: The case has not been test printed by me - please report back, should you encounter any difficulty.

I had to do some minor tweaks on the Top Shell part (-->V5). Please download again.

i found 2 problems:
1) user button has some object at upper surface which will prevent it moving
2) the rib on upper part at VGA place should be cut. otherwise will collide with connector.

I think, the front and back plates should be closer to the board, so it will possible to make holes more accurate and separate for each connector.

I think, if you expect the buttons printed inside with ability to move, then it should be ok to expect the case parts be close to board.

It seems you've cut place for VGA connector in latest revision.
But i think, you made the case too close to VGA, so even you had to put niche for connector. It's not a good solution. I like slim case, but this is too extreme. It's better to allow VGA connector to fit inside without niche. VGA connectors can vary allittle for different manufacturers, so it's better to use it's max dimensions as a cube. By the way, VGA has a rib on the front.

I'm thinking.. May be it's better to screw top part to standoffs? In this case you don't need that side ears, and the screwing to metal will be more robust and allow to screw/unscrew indefinite times.

Thanks for your feedback. I will take another look at this next year. I guess making the vga connector part more spacious has advantages so a heigher case makes sense.

I am a little unsure how many people will actually be able to use the case (being for XS sdram only). Therefore I like the universal case approach better at the moment.

Also personally I like the front/back panel approach in general, as one can modify the panels even without great 3D design knowledge. Then one does not have to print the hole case if one wants to test something new. :D

Also please consider that I am by know means a design expert. Anybody is more than welcome to come in with better ideas and solutions. :angel:

@Sorgelig - Nice spotting of the glitch in the button. I uploaded a fixed version for this (-->V6). Movable buttons should be printable now. :mrgreen:

Also the niche cut for the VGA should work fine. There is around 1 mm case wall left (more than 5 layers of printing material) - so no problem at all. I calculated around 0.5-1 mm wiggle room for vga connector tolerances. Should work for most situations I guess. However - of course it has to be printed and tested - before one can say: It is a fit. :mrgreen:

I think, it's better to make top half higher ~2mm, so you won't need any cuts of top part for VGA. And it will look much better. 2-3mm won't change the size visually.
Also note the VGA connector position. The bottom of hole should be higher. I think it should be symmetrical to connector on top and bottom.

About connectors holes - i didn't mean to glue the front and back. The whole concept of panels will be the same. Just put these panels closer to the board, so the holes for connectors can be smaller and repeat the connectors shapes. Since you expect that buttons with 0.1mm(or less) gap around to be ok, while gap around the board is 2mm which is huge, IMHO.
Panels can be thinner if it will allow to make more accurate holes.

Agreed. I will look into make it bigger. Making the panels thinner is an option, but I cannot promise much here. Making changes to the tolerances could impact a lot of things and would require more testing. We will see. As for the lower hole of the vga, that is kind of useful to have. Fitting and removing the IO Board requires some wiggle room for manovering and lining up the pins. I will send you a model for a panel with tighter hole, but I cannot promise that you would be able to assemble it in one piece that way :wink:

New version of the case published:

MiSTer XS Case v2 for SDRAM XS - extra slim - v1.1

All in all 4 mm higher than MiSTer XS Case V1. I also changed the panel cut-out for the vga slightly.

@Sorgelig: I attach my "unmodified" stls for easier customization (e.g. Panel without any holes).

Also find attached the OpenSCAD I use for the outlining of the case. This file can be used to test out tighter tolerances. :)

The code is a slightly modified version of the code found in this thing.
https://www.thingiverse.com/thing:1264391
My modification added asymmetric clamping of shells.

I'm not professional in 3D editing. I even don't know what that files for :)
I hope i will find some time to learn some basic 3D operations such as expanding surfaces. I can cut, but cannot expand yet :)
That's why i've asked to modify the case. I hope i will be able to modify it by myself some day.

Again, I understand. But my modeling skills are crude at best. The OpenSCAD file is a program that can be parameterized and run through a compiler to produce a shape of the case (output is stl). Great to experiment.

My take on this is that to get a slimmer fit (looking at the panels) one would have to redesign the hole case. Maybe rotating the pcb and using only Top and Bottom Shell would be best suited.

I am quite happy with the current design. Maybe I get inspired and will work on it in new cases someday later this year. However, should anybody be interested or has questions I am ready to offer assistance. 8)

Further improvements for case can include the panel with 2 widths. The thinner part will be inserted into case, and the thicker part will have same thickness as ribs on top/bottom parts, so when panel is inserted, it will make a flat surface together with ribs.

Long time lurker, first time poster. I just received my XS Case v2 from Thingiverse and using "Print a Thing" service and it came out pretty frickin good. I was lucky Print a Thing coupled my order with a 3D Print person who knows how to make pretty good prints. I love it! Nice job NegSol this case looks great! The tolerances are quite tight and good. And thanks Sorgelig for this amazing project of yours!

Thanks for your feedback. :D Glad you like it.

I could be wrong, but on the picture looks like the buttons are fused to the case. Or is it only the brightness of colour that give me that impression? Are the buttons moving freely?

Yes, they move freely. I thought I might have to crack them loose or something but they're fine.

Thumbs up - good to see that it worked out fine. Anyway I will release a lower tolerances version for people with less precise printer setups. :mrgreen: :mrgreen:

Here is exactly that: :megaphone:

For printer setups not able to print the finer, tighter original tolerances I added a Top shell with wider gaps between buttons and case. Top shells are downloadable from Thingiverse as usual. Enjoy.

Damn it Neg, you're really tempting me in getting a 3D Printer. I was so content getting stuff made from online printing services and worrying if it'll get printed properly. :lol:

Just have a question concerning printing! I want to order the extra slim to be printed next week, but I have no clue how much infill should be used to print it! What should be used for the best results?

I wasn't too sure myself, so I went with the goto 20% infill. Layer thickness is how smooth you want it, I went the ">0.2mm" since they could get the part to me quicker and even though it had some "salmon skin" I like the texture in this instance, gives it character.

Oh word, thanks man! I'll go for this set up myself! Maybe 0.2mm.

Thanks for the help!

20% infill should be enough. More infill will not give you any benefit.

I started work today modifying this so that the nano can be mounted to the top half using the 4 20mm corner posts on top of the IO 5.5 board.
I made it taller and wider so that a powered usb hub will fit next to the nano or the LL cool joy below.
Also, I am thinking it will just use the 4 corner posts to hold the bottom half together.
Waiting on the Cool joy or jim drews AIO board to be finished to do more. Thank you for the design.
