CloudShell4 Unauthorized

Post by hominoid »

Designing a 3d printable case that can handle two 3.5” drives is a challenge. I was tinkering with a cage style and a side supported design which got me wondering if a CloudShell2 could be converted for use with the HC4. Now, as well as being able to produce Cloudshell2 conversion panels, the Cloudshell4, Cloudshell4-Mini and MiniXL cases have been added and are printable on most 3d printers.

The HC4 fits beautifully with the IR receiver facing the front, the boot button accessible and plenty enough room to route two 22 pin SATA extensions to the HDDs. Only two panels need to be modified, the top where the HC4 is mounted and the IO panel. Both are small enough to be 3d printed. STL files for every case component are included below as well as DXF files for anyone with any kind of CNC cutter. If you don’t have a 3d printer or CNC machine the DXF file for the top can be used as a template to drill HC4 mounting holes in the original Plexiglas top. I have removed any unnecessary holes in all other components. Consideration needs to be given to the OLED display mounting and extra spacing around the IO connections may be necessary due to cable housing differences. I did this work as a proof of concept and have not yet created a prototype so proceed with caution if your going to use it. The SBC Model Framework is needed to view the Cloudshell4 model in OpenSCAD.

        Well nice 3D render indeed :), but the hard disks are mounted against the air flow, the first hard disk would block airflow from the back fan

          Thanks for the post but I'm not sure I understand your comment, the drives and the fan are mounted in the same position as the Cloudshell2. I personally have not had an issue with air flow in the CloudShell2 using 3.5" drives running an XU4. The HC4 requires even less cooling, if any, and the air flow exhaust is at the top front of the case. I think the only cooling that is going to be needed is for the HDD and that really only needs to be a low speed minimal airflow.

            Ah ! now I understand, you have to connect the hard disks with cables, I thought you want to plug it directly in the slot ;) You are very good in 3D do you have plots for the VuShell also ?

            This is close to what I would want in a CloudShell4:

            Instead of that ugly PCB, I want a 3.5" touch screen LCD panel. Also, the power connector should be in the back.

            I did a VU7+ shell as a hand held monitor for use with headless servers and sbc clusters. It also has a 100mm vesa mount on the back for flexibility. With a couple of minor changes it could accommodate the vu7a+ as well. I don’t have a vu-5a unfortunately.

              It’s a nice design. I was tinkering with a similar design but I found there are two potential issues in using a HC4 in that configuration. The sata connectors are positioned in a way which makes one of the 3.5 drives overhang the pcb significantly, well at the opposite end of the pcb you have all the io connections. So if you mount it vertically the IO connections are coming out the side. If it’s mounted horizontally they come out of the bottom having to enlarge the case size even more to accommodate 90 degrees cable bends. With 2.5” hdds the configuration could be done in a more appropriate size but you still have the cable issue. How about adding a vu7 or vu5 to the cloudshell4 running a touchscreen ui. The larger screen opens up a lot more possible display uses.

                    @AreaScout, Looks like I misunderstood, I see there was a product called the VU Shell in the past that was a wedge shaped case. I do not have any designs for it
                    but I did post the source and stl's for the VU7+ in the VU sub forum. viewtopic.php?f=101&t=40812

                      Thank you for the STL files, maybe you have one with a bracket so it can't tilt back ? Yes the VUShell was the wedge shaped one, mine broke falling down and HK doesn't produce it anymore :(

                        Yeah, give me a little time to figure out the best way to design a tilting bracket for this configuration and get it drawn. I got a couple of other things going.

                          The the initial design for the Cloudshell4 Vu7 side bracket is complete. The Vu7 can be detached easily from the CloudShell4 without any tools. When detached it allows for freestanding or handheld viewing.

                          I’m really starting to like this configuration so I decided to build a prototype. I have to add the Vu7a+ case and order some 22pin SATA cables. In recently using the Vu7+ touchscreen on a Cloudshell2, I noticed the unit can move when on a hard surface so a design for non-slip feet are in order. The oled needs a mount point and support for other Odroid SBC needs to be explored...CloudShell 2xtreme…??

                          Design files will be update as improvements to the CloudShell4 are made. Pictures of the bracket prototype on a CloudShell2 , stl’s and source files are located in the Vu7 Series Case and Bracket thread.

                          Uncovered some alignment issues with the io panel. Everything was adjusted based on an 8mm standoff for the HC4. It’s the same height as the standoffs that come with the cloudshell2.

                          Some of the openings were enlarged and everything seems to fit well. All the stl files were regenerated with a circle segment bug fixed in a couple. Continuing on while waiting for sata cables. OpenSCAD, stl and dxf files updated in op.

                          It looks cool, I would love to see a 5" touchscreen on the front that would give me the chance to display way more information on the display and the touch would allow the user to set fan speed in percent, program temperature set points and alarms, it could even be used to turn on/off the light's in your house, you could enable or disable to run Kodi when HDMI is connected a.s.o

                          I agree, looking at the HK display offerings in the recent past it was the best choice for a front display for this use. Were you thinking landscape or portrait?

                          I think the displays look poor when rotated to portrait but for this usecase it makes more sense.

                            That should be a 4.3" or 5" 480x600 SPI not HDMI driven display and it should be cheap, not easy to find the right one !

                              There are many 4.3 and 5" I2C touchscreens available at Digikey but they are expensive.

                              I like to reuse things that work well. In the embedded world that is usually not the way it works for cases. Each SBC often has it’s own case and they usually don’t house drives. It would be really nice for some uses like a NAS, if one could reuse a case when wanting to upgrade the SBC. This is the basis of wanting to explore what other Odroids could work with the Cloudshell4.

                                The Odroid-N2+, N2 and N1 can now be used with the Cloudshell4, as well as the Odroid-HC4 and XU4. Moving forward I’ll be looking at adding some accessories like displays and brackets, varies mounts, cable restraints and possibly 3d printable sides. The Odroid-H2 and H2+ use a very similar case for twin 3.5” drives so many of the accessories should be usable for it, like the recently published Vu7 series case and bracket.

                                With a level shifter adapter so the cs2 display can be used with boards with full gpio access like the n2+. I don't see any reason the usb3 to sata bridge shouldn't work already but I haven't tried it.

                                Now, as well as being able to produce Cloudshell2 conversion panels, the Cloudshell4, Cloudshell4-Mini and MiniXL cases have been added and are printable on most 3d printers. The Cloudshell4 and MiniXL require a 200mm print area. The DXF design approach has been retained so most of these cases should be able to be created with CNC cutting machines also.

                                Various changes have been made from the original HK Cloudshell2 design. All Cloudshell4 cases have 3mm thick side panels and have had the drive orientation rotated so that the connectors are at the rear of the case. The drive positions have also been optimized for each case and it’s intended drive types. Both the front and rear panels have been lengthened at the bottom to enclose the case and the Mini uses a case size matched 2.5” drive holder as the bottom of the case which allows for the use of standard adhesive feet.

                                An oled display mount is available and I have been also experimenting with an ir window to allow the use of the remote. It is the small square next to the display in the photo above. It does work but more testing is required. The case is printed using clear filament so it is not clear to me(no pun intended) if the front panel is allowing the signals to penetrate or if it is the window. It is currently disabled and not included in any of the provided stl files. If you want to try it, enable it in the OpenSCAD source file and regenerate the platter and then export the stl. 12” SATA extension cables work well, even for the mini.

                                Because of the additional case components(60+ dxf files) there could be many stl’s for all the possible case combinations based on the supported SBC: HC4, N2+, N2, N1 and XU4. The size alone is prohibitive for posting on the forum. Complete stl platters are included for the Cloudshell4, Cloudshell4-Mini and Cloudshell4-MiniXL for the Odroid-HC4 as well as Cloudshell2 conversion panels for the HC4, N2+, N2 and N1. Each case stl platter is large so use a tool to break out the individual component shells for printing. If your slicing software cannot split a stl I would recommend Slic3r for that purpose. The other stl’s for different cases can be generate from the OpenSCAD source file. The configuration for any given SBC and case is determined by a few options at the beginning of the source file.

                                Code: Select all

                                mode = 1;               // 0=platter, 1=model, 2=accessories, 3=debug

                                Notes:
                                All case keys and the HC4 top mount fan holes are meant to be tapped for 3mm screws. If you don’t have a 3mm tap, the OEM fan has 3mm nut shaped holes so a screw and nut can also be used to mount it.

                                When building a case configuration using OpenSCAD, you may receive a DXF error because the orignal files have a multi-line text entry that OpenSCAD doesn’t recognize.
                                WARNING: Unsupported DXF Entity 'MTEXT' (9) in "dxf/CloudShell2_RightSide.dxf".
                                It doesn’t cause any problems and doesn’t display. I have spent a limited amount of time searching the DXF files but haven’t found it yet to remove. It’s contained in all the original HK provided DXF files and I suspect it was a title block that didn’t get deleted correctly for some reason.

                                OpenSCAD, stl and dxf files updated in op.
