With theÂ explosive growth of 3D printing, and rapid manufacturing at the consumer level in general, physicalÂ objects can be designed and manipulated in a computer. Â She’s been using them for years, and asked for a pack, in case she looses one (printing a set of six takes about 15 minutes the example in the photo is an early print in black, instead of brown). Â Guess you could call it an “eyeglass arm pretensioner attachment”.

So, I quickly designed a clip that slides over the frame, and has a tapered nub to apply pressure to the arm (printed in ABS, so it has some flexibility). Tightening the screws didn’t do anything anymore. Â However, over time, the arm loosened and they would constantly slide down her nose. Â My mother has her favorite eyeglasses and is loath to change them. Â It was one of the quickest to make, but it was usedÂ a lot. Â Some of these are published on Thingiverse (linked from the post headings). Â Second, it’s of general household use, so mechanical assemblies, 3D printer parts, etc, were left out. Â First, it didn’t take me more than an hour to whip up the CAD model (and, in many cases, it took just 10-15 minutes), so it qualifies as a “quick hack”. Â I’ve chosen examples that satisfy two criteria. I’m often asked “what is aÂ 3D printer good for, isn’t it just a novelty”? Â So here are some examples of household hacks, in no particular order. Edit:Â You can also check the Hackaday.io project page for occasional updates. Â The source code for everything is available on GitHub. If this seems interesting, read on for details. Â I also designed a 3D printed enclosure with simple geometric shapes and used it as a further excuse to play with 3D print finishing techniques.

Â I was actually missing our old X10Â alarm clock controller (remember those?), so I decided to make one from scratch, because… why not?Īlthough the X10 Powerhouse controller’s faux-wood stylingÂ and 7-segment LED had a certain… charm, I decided to go more modern and use a touchscreen. I was overall very happy with these bulbs: decent Android and iOS apps and, compared to fancier solutions (e.g., Philips Hue or Belkin WeMo), theyÂ do not require any proprietary base stations, and you can’t beat the price! Â However, switching off the lights before falling asleep involvedÂ hunting for the phone, opening the app, and waiting for it to scan the network not an ideal user experience.

Â This turned out to be an excuse to play with theÂ ESP8266, which has inspired several hacks. A couple of months ago I picked up cheapÂ WiFi-controlled LED bulbs ( oneÂ amongÂ dozensÂ of very similar devices), after seeing them at a friend’s place.
