Rhino 4.0/AutoDesk Inventor
Wood (Maple, Pine...whatever you can find)
Metal Rod/Tubing 1/2" and 1/4 "(Steel, Stainless, or Aluminum)
Sheet Metal 16g or 14g (Steel, Stainless, or Aluminum)
Skills and Tools Needed:
Shop Bot 2 and 2.5D
5" Diameter Pipe
Sanding and filing
Step 1: Making a model
Once I gathered my measurements, I created a model in Rhino 4.0. The parts in purple will be made of wood and the blue, metal. From this model, you're going to create the part files for the Shop Bot.
Step 2: 123D Make
I considered doing a 2.5D for the round portion but since I placed registry holes in his body it is necessary to route this section in layers and then glue him together. This method of construction is perfect for 123D Make.
I saved my file as an STL, then imported it into 123D Make.
From there, you can input the size of your object, your material( it's good have your material on hand so that you can take accurate measurements) and how you want it sliced.
It will automatically draw the vector files for you based your parameters! (There will still be some clean up in V-carve) You will then save the file as an .eps or PDF.
Step 3: V-Carve
An endmill is an appropriate bit for the types of cuts I'm making for these parts.
Step 4: Shop Bot it!
This is to insure that my files are written correctly before I destroy any new material.
In addition, I'm still in the process of acquiring the tube for this piece and would like to get accurate measurements so that my registration holes fit around the tubing snugly.
As you can see on the individual layers, my part files weren't entirely correct, so some adjustments will have to be made before the finished piece is routed.
I then glued and mostly sanded the model to get a idea of how the finished piece should look. Yeah...not going with plywood.
In part 2, I'll being working with 2.5 to create the whale's tail!
