Given a 3D wireframe model in OBJ, STL, OFF, or OM format, osso generates 3D models for unique connectors at every vertex, as well as length for every edge.

###Compatibility osso is compatible with, and tested on:

• OS X (tested on 10.11)
• Ubuntu (tested on Ubuntu 16.04)
• Fedora (tested on Fedora 23)

##Installation

1. cURL the osso installer file, then run it!

   $ curl -O https://raw.githubusercontent.com/wieden-kennedy/osso/master/install && bash install
   
   # NOTE: If you'd rather redirect cURL to bash with a pipe (`curl foobar | bash`),
   # just know that in doing so, you will bypass all prompts for consent (osso
   # will go hog wild and install whatever it wants/needs to install). Up to you.

osso will walk you through installing all of its dependencies, and compile and install its own binaries into your system path. Once that's all done, you can start using it!

##Using osso osso comes with three object mesh models pre-installed, which can be found at /opt/osso/support/mesh/. These are a great place to start to see how Bucky handles creating connector models. We will use the icosahedron model for this walkthrough.

1. To get started, run the following command from a terminal prompt:

   $ osso /opt/osso/support/mesh/icosahedron.obj

   If you don't specify the model file as the first parameter, that's cool, just be sure to use the -m flag.

   $ osso -c -m /opt/osso/support/mesh/icosahedron.obj

2. By default, osso will create the connector models and stash the generated files under ~/Documents/__osso__/generated-{datetime_stamp}, where datetime_stamp is the time of completion. You can find the generated connector models under the subpath stl/.

   If you would like to have osso output to a different directory in the ~/Documents/__osso__ directory, you can use the -o (lowercase) flag:

   $ osso /opt/osso/support/mesh/icosahedron -o my_rad_model

   Alternatively, if you want to put the folder somewhere else altogether, you can use the -O (uppercase) flag:

   $ osso /opt/osso/support/mesth/icosahedron -O /some/other/path/to/my_rad_model

3. Import the generated connector models into Cura 15.04, rotating them so that the sphere (center of the connector) and the side with the most connections sit on the printer bed.

   ###Important Note

   Currently, osso doesn't number the connector parts, so it is
   important to note which connectors (0, 1, 2...n) are placed on the printer
   bed where. 
   
   For example, if you are printing 8 connectors at a time, you may
   place `conn0.stl` through `conn3.stl` in the first row, and `conn4.stl`
   through `conn7.stl` in the second, just to keep them organized.
   
   We have plans to remedy this in the future so that each connector is labeled
   when printed.
   

4. Load Cura profile cura_profile.ini from the generated folder using File - Open Profile....

5. Save G-Code File - Save GCode... to an SD card, and print on your 3D printer.

###(Re)Compiling osso's Dependent Executables If for some reason you need to recompile the dependent osso executable files, you can do so super easily by re-running the install file using the appropriate flag:

$ osso -c

Optionally, if you are working with osso on OS X, you can open up the XCode project and build the executables there. The XCode project is located at /opt/osso/src/openmesh/xcode.

###Updating osso If you'd like to do an in-place upgrade of osso, you can do so by running osso with the -u flag:

$ osso -u

Running the above will pull the latest code from the master branch down to your system.

###Removing osso It's pretty easy to remove osso, but, be forewarned, you will not be able to do so without some pretty passive-agressive efforts to deter you:

osso -r

Of Note: Removing osso will not remove its dependencies, and will not remove the folder of generated vertices (~/Documents/__osso__).
