3D printing is like cooking or like BBQ: It is more about barometric pressure, humidity and temperature than you might think of. To me, printing (and cooking) is a combination of art and science. And as with cooking, sometimes the result is not usable.
I’m very happy with the Ultimaker 2 printing PLA material. For a LED matrix project I have to use ABS as this material is suitable for higher temperature: PLA simply will not stand the heat produced by the LEDs I’m going to use. And here the joy ended: printing using ABS was definitely no fun. While the first small test print came out OK, I produced afterwards a pile of unusable parts because of warping :-(.
In “openHAB RGB LED Light Cube with WS2812B and NXP Kinetis” I started experimenting Kinetis boards, a LED cube diffuser and Adafruit WS2812B NeoPixel LEDs. That worked well, but I was not to very happy about the visual effect. So here is my next version: I wanted to have control over each side of the cube. For this I have built a cube inside the cube with a 3D printed structure:
Does everybody still know why in the ‘old’ days there was the need for running a ‘screen saver’ on the computer? With the modern LCD displays they lost their initial purpose. After “3D Printed Classic Mac Apple Watch Charging Station” I’m doing more ‘good old days’ 3D printing. The ‘elder ones’ might remember the “After Dark” screen saver software for Apple Macintosh and Microsoft Windows machines. Yes, that was 1991! For me most famous and iconic theme were the “Flying Toasters”:
Sometimes it is all about doing fun stuff: to carry and store the tinyK20 (NXP/Freescale Kinetis K20) boards needed for next course, I wanted to build something geeky: a MUFG capsule to store and duplicate Kinetis boards 🙂
One of the first machine I used for development many years ago was a Apple Classic Macintosh computer. My days of development with Pascal and Modula-2 are long gone. But with the availability of 3D printers I can print a Classic Mac :-). But now it is not used for development: I use it to charge an Apple Watch:
The tinyK20 boards are now used in several projects. Initially I was considering a commercial USB thumb drive enclosure for it. But this needed some tweaking of the enclosure so at the end it was not ideal. 3D printing is probably that hot topic for 2016. So why 3D printing an enclosure for that board?
