Still looks good. In fact, your 3d renderings are awesome! How about the USB thing? Might you make 2 revisions to add one with a notch for the USB port? Again, just throwing that out. I'm really not sure how many poeple have the USB version. I'd also ask about the JTAG port, but it seems unused at this point. I'm sure it'll be easy to remove the case anyway if a firmware upgrade was needed. Does it also protect the component row at the bottom of the chipset? BuffaloWing, you're doing a great job. Keep it up. I'd gladly jump in for funding of this project...within reason, of course.
Thanks again! Just remember the actual 3D print will be a bit rougher in appearance due the limitation of current technology (at least for this particular process). As for USB cutout and JTAG port, something definitely can be done. I originally designed prototype shell to satisfy my own need so I didn't think about too much about including features other might care. If not for the encouragement from you and other forum members I would of stop at my prototype. I'm not sure what you mean by "protect the component row at the bottom of the chipset" question. Are you talking about the bottom side of the PCB? I was thinking of just applying vinyl label on the expose traces. View attachment 4915 As for funding, no need to worry about it. This project is relative inexpensive. It's just my time and effort. It only cost me money when I need it printed. Does anyone know if the forum marketplace rule applies here if I provide the link to allow people who are interested to order the part directly from printing service?
I don't think you'd need to necessarily post in marketplace if you are just directing people to a third party site for purchase, could be wrong. down to buy though, please keelp us posted
Well, I meant that little row of capacitors or resistors about midway through the TED. But looking at that semi transparent image, looks like you got it covered...so to speak. I'm definitely watching this thread.
Great job on the design! Just one thing, the reset button seems to be a little bit difficult to reach. Personally i will try something like stoneAgeGamer...
The reset button is easily accessible if you look at the first prototype pics. The renderings do it no justice.
I'm still waiting for my test print to arrive. Meanwhile I've finished designing other variations. I'm not sure if I will ever have them printed as I don't have JTAG nor Mini USB-B jack & its corresponding controller installed. Here are some renderings:
Nothing short of amazing there, BuffaloWing. Really loving the top one. If anything, I'd personally go with that. Awesome job! Please share your next print with us. I'm as excited for this as I was for the TED release!
I've got some good and bad news. First the good news: My new test print arrived today. Overall the fitment is good. The reset button area is now more accessible. The new recessed "panel line" came out fine. Now the bad news: The printing service seem to have the part printed in an upright orientation which give the shell a striated look which might be alright if you are into brush aluminum look. I'm actually alright with this but the real issue is that when I screwed the shell tight into the PCB, I noticed the corner at the microSD area lift about a couple millimeters. I feel the orientation of the print contribute to the bowing of the shell. This effect is magnified as the shell can't be screwed closer to the corner due to the position of the microSD slot. I had the part dyed by the print service which look fine except it seem to stain your hand if you have sweaty hand. It's probably residue left from the fabric dye process they used.
No, it doesn't affect the card at all. It's more of an aesthetic issue. Upon more inspection, it seems like the small notches I incorporated to clear the two soldering points on the edge of the microSD slot were too shallow on this print. So the two blob of solders is effectively acting as wedges that are propping up the corner of the shell up. I'm am really at the limit on how big the the notches can be due to the printing tolerance. The random choice of print orientation by the print service also make this worse. This is something I can't control. I guess some possible solution is to: A) desolder excessive solders as this is may vary for different PCB, B) Shave a little bit of the plastic off the shell using a hobby knife, C) Stiffen the shell more, D) All of the above.
butfluffy and derekb, thanks for the interest. I'm trying to iron out all the kinks so you don't have to.
I'd say let the end user do it, seeing that it might be a by-case (pun) scenario. In other news: DO WANT!:victorious:
