Mash, Mish, & Mesh STLs with Matthew Plummer-Fernandez’s Disarming Corruptor Tool #3DThursday #3DPrinting

Disarming Corruptor 2

Mash, Mish, & Mesh STLs with Matthew Plummer-Fernandez’s Disarming Corruptor Tool:

Disarming Corruptor is a tool for making reversible damage to your STL mesh file. This means you can obliterate it into something totally unrecognisable, share it online under its new guise, and selectively distribute the key code to recipients so they can reverse the damage and retrieve the original object.

In a time of prolific online espionage, crackdowns on file-sharing, and a growing concern for the 3D printing of illegal items and copyright protected artefacts, DC is a free software application that helps people to circumvent these issues. Inspired by encryption rotor machines such as the infamous Enigma Machine, the application runs an algorithm that is used to both corrupt STL files into a visually-illegible state by glitching and rotating the 3D mesh, and to allow a recipient to reverse the effect to restore it back to its original form. The file recipient would need both the application and the unique seven digit settings used by the sender, entering the incorrect settings would only damage the file further.

When patent trolls and law enforcement agencies find these files on sharing sites they will only see abstract contortions, but within the trusting community these files will still represent the objects they are looking for, purposely in need of repair. It could also be used to symbolically decommission files and throw away the keys, or to make something inoperative yet still recognisable so that other users would have to request a key to put it into use.

DC is free and available for Mac OSX, [ and I’m currently working on exports for Linux (32, 64) and Windows (32, 64) ], it was made with Processing and the HE_Mesh Library.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
