If you like the Fixer’s Manifesto then you can also look at pictures of people holding it here, if that’s your thing. If you want to fork/hack/improve it you can do that on the github page. If all of that is just to “free as in beer” for you then you can also buy a print from Sugru (it comes with a pink pen for making edits…yeah).
You may or may not already know who Josef Prusa is. If you’re reading this…odds are you know.
He’s taking his “3rd Iteration” (i3) RepRap to the Open Hardware Summit, and the coolest thing is that it breaks down into two flat sections!For those who are interested in the ever increasing diversity of the RepRap family tree, the i3 seems to be based mostly on the design of Nop Head’s Mendel90.
There isn’t much information available at the moment, but it looks like Prusa has created some special components, particularly in the extruder. Here are some notes, and the github. And here it is printing a giant vase…
Unlike software, hardware projects cannot be entirely defined, or contained within, the computer. That’s a shame because there are some really great tools for managing software projects.
Gary Hodgson has prototyped his proposal for using github to manage hardware projects. He called it githubiverse and, appropriately enough, hosted it on github. Here is an example of it functioning to track Mechanical Movement #27. All the files are on github and this custom webpage displays whatever is up to date.
An interesting advanced use case is the ability to use the same core template across many projects. You could fork the githubiverse-template project and edit the html/css as you wish. Then, in each project’s gh-page branch create a submodule referring to this fork. All that’s left would be to create a _config.yml file with the details in the root project gh-pages branch and an additional entry defining the source of the jekyll site as being the submodule folder.
…as reminding me of this Dilbert cartoon.
A 3D printer is, at heart, a prototyping machine. They will never be able to compete on volume alone.
What they can compete on is high-volume customization. Josef Prusa, the designer of the Prusa Mendel, wrote a Python script to automatically add a custom pair of initials to the many whistles he prints out as gifts.
The great thing about open source is that people do cool stuff like this and then give it away! You an download the WhistleGen program Josef Prusa wrote from his GitHub repository. Perhaps someone could modify it to take advantage of two-color or multi-color extruders.
