A company named MicroMark makes small version of trades tools...
That's pretty great. Even though I don't need 90% of those tools for anything, I sure enjoyed perusing the marking and measuring section.

I kinda want that contour measure tool, though.

Same! Instead of exhaustively measuring things, was just thinking of separately copying curved parts onto engineering paper, scaling it to the correct size, and compositing multiple images like that in Photoshop to get front views and profiles. (I don't have a scanner, so I sure hope that my iPhone camera and perspective correction will work...)

I blew a little money on it, and I'll report back.

Update: oh god they have a screw pitch checker!!!!! Finally I can figure out which standoffs to get for my PowerBook...

I went to go download a 68040 storage tray, but the model is now gone from Thingiverse 🙁

So, I decided to start another one, based on a tiny thumbnail of the image:

cpu-tray-for-4-pcs.jpeg

Measured one of my CPUs and have it a smidge of wiggle room, which proved to be just enough:



Printed this first draft to even make sure a 68040 will fit in it properly:



Seems to work:



There's a pleasant small snapping into place for a decent hold. I'll need to print another one and possibly refine the nested legs so they can stack/act like a lid, just in case.

The pins are surrounded but not compressed at all, allowing for multiple layers to stack without touching at all.

I wanted this as an alternative to foam pieces where the pins just get bent anyway... It'll still need to be stored in ESD protective bags, obviously, but it's a decent storage solution, I think.

Once I test and work out the kinks I'll post an STL or Thingiverse link. I thought about trimming it up a touch, but at only 20 g of material at 30% infill and minimal supports, I don't want to make it weaker, so input is welcome.

Well, some refinement is in order:


I have some weird trapezoidal action happening on the bottom feet, which I suppose could be a nozzle height issue. Tried to slide the feet onto the corresponding notch on the top and the foot just snapped off.

Alright, I think I've solved the stacking issue:
  

Above is R3. R2 had some issues with it actually grabbing the ceramic of the CPU below it when it snapped into place. One last iteration test I want to make is to see if it's better putting the larger feet on the bottom. Both were "single" holders to save PLA and time.

From there, I may end up adding a floor, maybe not solid, but something to prevent pin damage during handling. I mean, depth isn't an issue, there's enough clearance for the pins, but at least putting in an "X" or something for a floor , or maybe covering the pins, and then an "X" over the plate (these aren't heat spreaders... right? it's like the plate over the die covering the connections IIRC).

This is a neat project!

I wonder if something similar could be designed for more modern CPUs, such as the Core2 Duo, Athlon, etc., as I have many of those floating around loosely (the C2Ds don't have pins, so bending isn't an issue, but they can still be damaged via ESDs and such).

Hi there,

Has anyone recreated the power buttons for the 8100 series? I'm getting a Powermac 8100 soon but the buttons are missing from the case. The part seems to be "Reset/Interrupt 922-0843"
If anyone got the .stl files for them, can you please refer me to them?

Thanks,

Yuffi.

msata to 2.5" Holding Bracket. I found one design for sd-card and made one for the msata which i prefer to use. I based of the outer bracket on: https://www.thingiverse.com/thing:3040182 

was alot of trial and error (trash bin is full of prints hehe) because the msata version is harder to fit and doesn't have a hole to fix it with. 

I could just snap it in printed on PETG. Support is needed to print it.

Adapter is: "adaptare 46235 mSATA-SSD" found on Amazon for example.

Here's an enclosure for a PowerBook PB 1[4-8][0,5]c? li-ion battery I drew. It's expected to be used in conjunction with the locking tab from an original battery. Thread with more details over in the PB forum:

I’ve finally finished this model after two years of working on it 7/18/18 is the date in fusion360!

Macintosh Quadra 700 micro

for the pi zero

https://p3d.in/u/zero82386
I never knew you couldn't download the models from P3D because I don't have a pro account! :-O

Thanks to @Aladds for pointing this out!

Here are the STL files in a zip file, also linked to my drop box in case this upload isn't allowed

Thanks!

Thanks again! I’ve already printed the lid, and the main case is about 5% in. This is really well designed and it’s coming out very well! (We have noticed that the printer is slightly wonky, though, but we’ll fix that afterwards because it’s not entirely noticeable and the lid won’t fit if we change it now!

that's amazing!! I still haven't figured out a solution to keep the lid on if you stand it vertically, mine are spray painted since I had blue/black/red filament, but I also have this little stand (with feets!) that can help too. I thought about hot gluing magnets inside but haven't gotten around to it yet. I'm really excited to see someone else working on it!!

Still got to print the little bits, plus I now see what you mean about the lid. I would imagine the feet’s will hold it all together, though?

they should hold it together! It’s not the most snug fit but it worked when I printed them! That looks awesome! I am glad to see the mounting holes worked! I didn’t have a chance to reprint after adding them (i drilled mine)

I found a little LED which fits in the corner hole, still need to pop a little hot glue to hold the wires neatly but otherwise it’s good.

I do still want to make a little door for the MicroSD card, and fit/wire up some buttons

I made a door for the MicroSD card slot!

Edit: Added STL

That is awesome! I'm so happy to see it all in white! The feet look so much better matched like that. The SD door is a great addition to the project! I will have to print one myself, but it will be red until its warm enough out to paint!! Thank you for sharing the STL file!

I have a pZero sitting around. This will make me unlimber the 3D printer... 🙂

I have started to create a 3.5" "AppleColour High Reoslution RGB Monitor" - I've even found a 640x480 HDMI LCD module to go inside - although sadly that'll take weeks to get here on the slow boat from AliExpress.

I'm even planning on giving it speakers so I can use it as a mini alarm clock.

As an aside, I have noticed that a bare-metal Amiga emulator seems to exist which runs on the Raspberry Pi without Linux. Now as some people know, some Amiga emulators can emulate a 68k Mac.....
