3D printed Canning Jar Accessories

Using a 3D printer for practical reuse in the kitchen

There is a fantastic series of posts from Alex over at the ProtoParadigm blog featuring practical things you can do with a 3D printer. This isn’t about wowing people with the latest high-tech advances. It’s all about getting down to the nitty gritty and using that 3D printing versatility to get things done.

So let’s get practical with our printers and extend the function of those ubiquitous glass jars. Documenting each solution with a brief but informative summary, Alex kicks things off himself with some easy-to-open, watertight lids. He then turns to Thingiverse for inspiration, and follows through with bank lids, a fly trap, a sprouting lid for growing seeds, straining and shaking lids, and even a fermentation lid that allows for exchange of gases.

Further exploration on Thingiverse will uncover an even greater diversity of canning jar accessories, from sippy cups to funnels and more. Check them out, and build some of your own!

Ben Heck’s portable 3D printer

It’s alive! The Briefcase Printer revisited and heading to Kickstarter

It’s hard to go far in the DIY gadget world without hearing about the exploits of modder extraordinaire, Ben Heck. Famous for squeezing almost every electronic device imaginable into a briefcase, his latest efforts revisit a project to build a fully operational Briefcase 3D printer.

An earlier attempt did have its successes, but Ben always knew he could go further with this particular project. And now he has.

The Briefcase Printer folds out from a neat 4.2 x 18 x 14 inch frame, and boasts a 200mm2 build platform. It’s able to run autonomously by reading files off an SD card, or for more control and a smoother user experience, the onboard Arduino 2580 Mega can be connected directly to a computer.

It’s all explained with Ben’s trademark enthusiastic delivery in a comprehensive video after the break.   (more…)

How to: design a laser-cut box for your DIY electronics project

Who doesn’t like putting things in boxes!?

This mixer rehousing project is the perfect example of what you can do with a laser cutter and an online box-making app. If you prefer to use a tool integrated into Inkscape to make your finger-jointed box template, check out this sweet plugin.

With tools like these it’s getting easier and easier to design your own project enclosures ready to be shipped from your Personal Factory.

Variable speed bike sprocket

Give your single speed bike a boost with some parametric goodness

If there was an award for parametric design that made riding your single speed or fixie bike usable on gradients greater than 5 degrees for people other than Olympic athletes, then Jason DeRose would surely take it out with his variable ratio mechanical gear design.

DeRose, a software developer used Python and employed mathematics and geometry to work out the position of the sprocket teeth to craft his design. As part of DeRose’s design process, he then extruded the linework into 3D in Blender. He has also released the project files as open source on launchpad to allow others to build upon it. (more…)

DIY DNA with Arduino

PCR thermal cycler using off-the-shelf parts

This is another one of those projects that makes me think “who cares what it does, it looks awesome and I want one.” In this case it turns out to be far awesomer than I could have imagined: it’s an $85 DIY Arduino-powered DNA-sequencing device. Complete with comprehensive build instructions so you too can sequence your own genome. Amazing!

FoldaRap: portable 3D printer

A 3D printer suitable for secret agents?

This is the first 3D printer I’d consider worthy of Ian Fleming’s Q character in the world of 007. The FoldaRap is a derivative of the RepRap project, the first to be a truely portable 3D printer. It is designed to fit within a tough travelling case. (more…)

Ambika – open source polyphonic synth by Mutable Instruments

Open Source makes it sound delicious

Mutable Instruments are back with a new DIY-friendly open source synth and it looks and sounds amazing.

We’ve seen Mutable Instruments before around here before: there were a wealth of laser-cut Shruti-1 enclosures rolling out the Personal Factory gates about 18 months ago. It will be great to see what cool designs people come up with to house this new machine!


Sounds after the break…

TED: Massimo Banzi talks Arduino

How Arduino is Open Source Imagination

Arduino has arguably done more to change the DIY electronic landscape than any other open source device. We’ve often encountered this modular hardware wonder, popping up as an integral component in many 3D printers as well as being at the core of some of our favourite DIY projects.

In the trademark affable manner that he is famous for, Arduino co-founder Massimo Banzi talks through the ever-widening scope of this versatile system.

“(Arduino is) …the equivalent of sketching on paper, done with electronics”

From the humble beginnings in an Italian cafe to an incredible diversity of projects being run by all kinds of hackers, makers, enthusiasts and professionals… whether it’s the pre-teen kids tinkering in their bedrooms, high-school students sending satellites into orbit or multi-million dollar global corporations pushing the boundaries of scientific discoveries; Arduino can be found at the heart of a new revolution.

Watch this neat 15 minute TED talk overview from Massimo Banzi, on Arduino’s role in the new paradigm of Open Source Imagination.

CNC machined Analog Structures

Resource efficient structures

Analog Shelter is part of New Zealand designer Daiman Otto’s Analog Structures project. The cladding system Feel Free was designed to respond to the Shed Light exhibition brief, currently on show in Federation Square in Melbourne, Australia. His aim is to produce a series of small DIY, standardized and customisable buildings that anyone can put together without the need for a set of saws and building tools. Feel Free’s exterior cladding encourages interaction by allowing people to touch and manipulate the exterior polyproplyene panels. (more…)
