This project was born of a desire to try my hand at modeling an object in 3D and then bring that object to life using a 3d printer. The Ossein Lavallier (Ossein meaning bone and Lavallier meaning necklace) is the result.
In the steps that follow, I will attempt to explain the creation of the 3D model in Rhino and the resulting physical object printed in 3D. It is my hope that after reading this, you too will be able to create something similar and of your own design.
If I had to guess, I'd say the model took around 8 hours to create in 3D, with a learning curve. The physical model took 15.5 hours in the printer. I am new to Rhino so I am sure that the 3D model could have been completed much more efficiently.
This tutorial assumes at least a beginner level of familiarity with 3D modeling and Rhino, with the user having played around with the basic commands. Prior to undertaking this project, I had used Rhino for roughly 6 hours, so something of this scale is certainly possible for a beginner. While this is my first actual Rhino model, I have previous 3D experience in Sketchup and older versions of Maya.
FOLLOWING ALONG USING IMAGES
The screenshots have the command line in them at the top left of the image. You can look there for some more info on commands I am using. If you are attempting to model something like this, make good use of your SNAP, ORTHO, PLANAR, and OSNAP settings. I jumped back and forth through these, changing setting as needed. The tabs showing the settings for these tools can be seen at the bottom of each image.
The images tagged in each step are numbered on the lower right corner so you can follow along with the instructions.
When viewing the images tagged to each step, make note of the viewport so you do not get confused. Working in 3D is all about knowing what direction your looking in. I jump back and forth between wireframe and rendered viewports, as it useful to change the display setting of the viewport from time to time. Working in wireframe mode, switching to rendered, then to ghost, etc. helps you visualize the model better and you can see hidden flaws that may go otherwise unnoticed if you are working in just one mode all the time.
