There are dozens of different 3D printable cases out there for the Raspberry Pi, but the BeagleBone Black, as useful as it is, doesn’t have as many options. The folks at 3D hubs thought they could solve this with a portable electronics lab for the BBB. It opens like a book, fits a half-size breadboard inside, and looks very cool.
The guy who 3D printed his lawnmower has a very, very large 3D printer. He now added a hammock to it, just so he could hang out during the very long prints.
There’s a box somewhere in your attic, basement, or garage filled with IDE cables. Wouldn’t they be useful for projects? Yep, only not all the wires work; some are grounds tied together, some are not wired straight through, and some are missing. [esot.eric] has the definitive guide for 80-wire IDE cables.
Like case mods? Here’s a golden apple, made out of walnut. Yes, there are better woods he could have used. It’s a wooden replica of a Mac 128 with a Mac Mini and LCD stuffed inside. Want a video? Here you go.
If you have a 3D printer, you’re probably familiar with PEEK. It’s the plastic used as a thermal break in non-all-metal hotends. Now it’s a filament. An extraordinarily expensive filament at €900 per kilogram. Printing temperature is 370°C, so you’ll need an all-metal hotend.
It’s the Kickstarter that just keeps going and going and going. That’s not a bad thing, though: there really isn’t much of a market for new Amiga 1200 cases. We’ve featured this project before, but the last time was unsuccessful. Now, with seven days left and just over $14k to go, it might make it this time.

Nice–could probably use that PEEK filament to make HPLC accessories.
If you’re just looking to make holders and things, PLA works fine wrt solvent resistance. It gets a little mushy on the surface but parts won’t really break too quickly. (source: dumped strong organic solvent all over a custom FLASH chromatography replacement part that I printed)
That “new Amiga 1200 cases” which never turns yellow reminds, what was the plastic that they used in the 90’s that always turns yellow ? They used it for beige monitors, keyboards, mice, plastic PC cases.
I believe the discoloring was due to bromine compounds used as fire retardants, and not the plastics themselves.
The yellowing isn’t permanent anymore either. Retrocomputing enthusiasts figured out that a mix of hydrogen peroxide and OxiClean will cosmetically reverse the oxidation. (Search for “Retrobrite”.)
Fun fact – OxiClean turns into hydrogen peroxide on contact with water, heheh. So, mixing hydrogen peroxide with OxiClean just gives you more hydrogen peroxide XD
You’ve got to admit, a walnut Macintosh will never turn yellow.
I am confused as to why anyone would spend that amount of money for PEEK filament. The whole point of 3D printing is for cheap prototyping and one-ofs. It would be a hell of a lot cheaper to print in nylon (with fantastic mechanical, heat, and chemical resistance properties) or print in any other material and mold it (assuming geometries allow).
From the Golden Apple: “The Macintosh 128K, originally released as the Apple Macintosh, was the first personal computer released by Apple.” Fail. Also, zink zinc.
I think walnut was an excellent wood for it.
Woot! Thanks for the mention!
Hope some hackers out there find the info useful!
